Plot

A comic caper about Happy Singh, a Punjabi villager who goes through a series of misadventures and eventually becomes the King of the Australian underworld.

Happy Singh lives in a small village in Punjab. He is always compassionate and helpful, but often ends up causing more damage, so much so that the Village Panchayat unites to reprimand him. When the community gets news that one of their residents, Lakhanpal Singh, is an underworld don in Australia, they decide to delegate someone to counsel him. The villagers choose Happy so they can get rid of him. Happy's ticket and other costs are paid for, and the Panchayat even asks a reluctant Rangeela to accompany him. Due to a mix-up, both end up in Egypt, leading to romance in Happy's life when he meets Sonia, a criminologist who would prefer to have criminals killed than reform them. Both friends find their way to Australia, where they locate Lakhanpal, who humiliates them and asks them to leave. Both befriend a boutique owner and live in her house. When rival goons attack Lakhanpal, Happy rescues him and gets him hospitalized. Lakhanpal recovers, but is paralyzed. His goons comically misunderstand that he wants Happy to be Don, and he undergoes a transformation and moves in to live a wealthy lifestyle in Lakhanpal's mansion. When the boutique owner's daughter returns home with her fiancé Punit, Happy plans a charade to make her believe that the mansion belongs to him. Happy's life soon turns upside-down to be none other than Sonia herself. Being aware of Sonia's dislike for criminals, he has no option but to plan a lavish wedding for her, while rival gangsters and even some of Lakhanpal's goons plan to get rid of him.—rAjOo (gunwanti@hotmail.com)

Lakhan "Lucky" Singh (Sonu Sood), is the king of the Australian underworld. He is accompanied by his Sikh mafia associates, Julie (Neha Dhupia), Lucky's brother Mika (Jaaved Jaffrey) who cannot see or hear properly (from his left ear), Pankaj Udaas (Yashpal Sharma) who has gone through every imaginable tragedy in life, Raftaar (Sudhanshu Pandey), Dilbaugh Singh (Manoj Pahwa) and Guruji Gurbaksh Singh (Kamal Chopra). Julie wants a break in Bollywood and wants Lucky to make a call to a producer or a director to cast her as the heroine. Lucky keeps Mika around as Mika has already taken 6 bullets for Lucky on his chest. On his birthday, an assassin attacks Lucky, but he manages to escape and catches the assassin.

In a small village in Punjab, the birthplace of Lucky, lives another Sikh, Happy Singh (Akshay Kumar). Happy, though good at heart, has unintentionally caused many problems in the village, and the villagers are fed up with him. A village boy Tinku (Khayali Saharan) is meeting the family of his prospective bride, and his mother (Dimple Bagroy) wants to cook butter chicken for them. The only problem is that the said chicken has escaped. Tinku summons Happy to catch the chicken, but he ends up destroying half the village in the process. Happy's grandfather Gurucharan (Gurcharan Dardi) is the Sarpanch of the village and has to fork up the damages. Eventually, the villagers know that Happy is pure of heart and cannot doubt his intentions. He is the life of the village.

The villagers decide to send Happy on a long trip to Australia with his friend Rangeela (Om Puri) to bring Lucky back to Punjab, which will keep Happy out of the village for some time and bring peace to the village. The village had seen the news of attack on Lucky's life, due to which his grandfather had a heart attack. Lucky had gone to Australia to earn an honest living, but someone slipped drugs into his bag and Lucky was caught at customs. Lucky was jailed and he took to a life a crime to take his revenge. The villagers believe that the news of the heart attack is the best opportunity to bring Lucky back home. Happy is an emotional person and agrees that Lucky has to be brought back to save his life and to restore the health of Luckys old parents. He vows not to return without Lucky.

At the airport, Happy's and Rangeela's tickets to Australia are accidentally exchanged with those of Puneet (Ranvir Shorey), who was to fly to Egypt. After they reach Egypt, the duo realize their mistake. The authorities get them tickets to Australia and also a one-day visa to Cairo. In Egypt, Happy meets Sonia (Katrina Kaif) and falls deeply in love with her. But he does not express his love to her.

Leaving her behind, he heads to Australia to meet Lucky. Lucky refuses to return to his hometown and throws Happy and Rangeela out of his house. Penniless, Happy finds warmth and affection in an elderly lady Mrs Singh (Kirron Kher) who provides him with food in spite of being a stranger.

Lucky winds up in a hospital, paralyzed, after a series of violent incidents that Happy has caused. In one of these incidents, his head is bumped severely, and the trauma from the resultant concussion is what paralyzes him. Unexpectedly, it is Happy who is given the position of the "Kinng", by Lucky's associates, who misread Lucky's intention to kill him, much to Lucky's chagrin.

The lady who helped Happy is obviously worried and depressed, as her daughter is returning from Egypt with her wealthy boyfriend, Puneet. The daughter does not know that after the death of her father years ago, her mother had become poverty-stricken and been reduced to work as a flower seller. She is worried her daughter will discover they are now living in poverty due to her father's death. Happy gives her Lucky's spacious house and makes all his mafia associates work for her.

The lady's daughter arrives and to Happy's horror, she is none other than Sonia. Heartbroken, Happy is forced to make a show of happiness to Sonia. Puneet says that he too would have had a good time with Happy and Sonia in Egypt had his ticket to Egypt not been exchanged in the airport, because of which he had ended up in Australia. Puneet had always been jealous of Sonia being with Happy; however, he doubts something is going on between them.

Meanwhile, Lucky's gang members spend enough time with the kindhearted Kinng for most of them to be reformed and give up lawless lives in favor of law-abiding ones. In spite of herself, Sonia falls in love with Happy and the truth becomes difficult to hide. Puneet sets his heart to marry Sonia. Sonia gets trapped in an emotional tug-of-war between Puneet, who loves her, and Happy, whom she loves.

In the confusion, Happy's associates reveal to Puneet who they are, and that Happy is the Kinng of the Australian underworld, not a manager as Puneet had believed him to be. Puneet, in turn, reveals this to Sonia, who has become aware of her own poverty.

Soon Puneet meets Mika, Lucky's other brother, who agrees to kill Happy. Puneet's motives to kill Happy, however, differ from Mika's. Puneet wants to kill Happy to keep Sonia away from him, whereas Mika wants to kill Happy to make himself Kinng.

On the dawn of the wedding day, the sound of gunshots firing can be heard. Happy takes Sonia in order to save her-and unknowingly, both run around the fire seven times, essentially getting married. During all this, Lucky's head is bumped, and the trauma-induced paralysis he had suffered from is relieved.

Suddenly, Mika turns up on the spot, ready to kill Happy, armed with a gang and his new special glasses and hearing aid. As he is about to shoot, Lucky steps up and stops him. Then a dialogue ensues between Mika, Happy, Lucky, and the associates of the Kinng.

Happy tells him that being the "Kinng" is not as great as it may seem and explains to him the characteristics of a true Sikh. Lucky confesses that he had always found being Kinng a source of misery, because a true Kinng fights for others, not for himself. Overcome with remorse, Mika drops his gun. Happy and Sonia get married and Lucky and his gang members return to their homes in the village.
