Tom (Josh Duhamel), Darcy (Jennifer Lopez) and their families gather for an ultimate destination wedding on a private island in the Philippines. The wedding party includes Tom's mother Carol, father Larry (Steve Coulter) sister Jeannie (Melissa Hunter), and friend Ricky (Desmin Borges). Darcy's side includes mother Renata (Sonia Braga), father Robert, and sister Jamie (Callie Hernandez). Robert has brought his girlfriend Harriet to the wedding.

Robert also invites Darcy's ex-fiance Sean to the wedding and he arrives in a helicopter. Sean has a jet-setting global career, while Tom's contract with his professional baseball team has just expired and he is technically homeless. Darcy and Sean worked together in the Peace Corps and were even engaged in the past.

Tom and Darcy are financing the wedding themselves, and Tom is obsessed with making everything perfect. Darcy's mother says that she should have taken her father's money and hired an event manager. Renata is a bit of a snob and looks down upon Carol, who is travelling out of the country or the first time.

The rehearsal dinner is a disaster when Tom makes a toast which was not funny, and everybody ended up liking Sean's toast. Tom spends the entire night finishing pineapple centerpieces for the wedding. Tom is bothered that Darcy was engaged to Sean in the past. Darcy says that Sean started working with Robert and then changed. He only cared about status and money and so Darcy broke up with him. Ricky is Tom's best man ad Jamie sleeps with him the night before the wedding.

Darcy summons Tom to a secluded part of the Island for a talk. She says that she is having second thoughts, and Tom agrees saying that they have been arguing more the last few months than they did in the first 4 years of their relationship. Darcy is sick of Tom trying to make everything perfect, while Tom says that Darcy doesn't even care about the wedding. Darcy says that she never wanted a big wedding as she is a grown woman. She never wanted Robert walking her down the aisle, or a big princess dress or even a wedding registry. She adds that she went ahead with it as she loved Tom. Now Tom wants to call off the wedding, and Darcy throws her ring at him, which he catches.

Just as the couple are away arguing about the wedding, their guests are taken hostage. The pirates push all the wedding guests into the pool, which they use as a prison. The pirates demand $45 million dollars from Darcy's wealthy father Robert (Cheech Marin). He refuses to pay until he has proof that Darcy is alive.

As they try to evade recapture, Darcy and Tom air their respective doubts about the wedding. Darcy and Tom are captured apart from the wedding party, but manage to escape their captors, killing one of the pirates. Darcy and Tom's hands are tied, and Darcy is holding a grenade in her hands without a pin. Darcy gives Tom a mobile phone that she had hid in her underwear before being captured, but the island has no cell reception. They head to the highest point on the island to find reception, but the pirates chase them, and they have to use the zip line to escape. Darcy drops the grenade on the pirates and kills 2.

They reach the wedding venue and find all their guests have been taken hostage. They hide in the kitchen where they try to use a meat cutter to cut their ties. But Tom ends up slashing his hand and Darcy falls unconscious from the sight of blood. Their cries alert the pirates to their presence. Tom and semi-conscious Darcy work together to kill another pirate who comes to investigate the noise from the kitchen. They then go to manager's office to find internet but have no luck.

Margy (Selena Tan) the manager pulls Darcy and Tom into a secret vault under her office. Margy says that Tom knew that there was a pirate attack at the island even last season. Cornered hiding in a vault beneath the manager's office, Tom surrenders to them so Darcy can stay hidden.

When he rejoins the rest of the wedding party, Tom reveals that Darcy's ex-fiance Sean (Lenny Kravitz) had hired the pirates. Tom had found Sean's invitation card in the pockets of one of the killed pirates. Tom suspects that Sean orchestrated the entire attack to steal money from Robert.

With his plot exposed, Sean goes to hunt down Darcy in a helicopter, taking Robert's girlfriend Harriet (D'Arcy Carden) as a hostage. Meanwhile, Darcy joins Tom and the rest at the pool where she and Tom admit that they still want to marry.

The wedding party members realize that Harriet was in on the plot with Sean. Tom asks the two pirates standing guard to let them complete the wedding ceremony, and Robert says that he will release the money if they let them get married. As the guests sing "I'll Be", Tom and Darcy rush the pirates, and Darcy takes a grenade off one. One pirate surrenders, the other runs, then begins firing on the venue.

Tom's mother Carol (Jennifer Coolidge) grabs a weapon from the ground and returns fire. Darcy throws the grenade in the air so Tom can bat it at the pirate, who is killed in the explosion (which also sets off the fireworks that had been staged for the wedding celebration).

As the wedding party goes to safety, Darcy and Tom race to get help, but are confronted on the dock by Sean. Tom fights him, then Tom and Darcy escape in a boat. Harriet tries to stop them in a helicopter. Sean, who had managed to stay with them by grabbing a mooring line, climbs aboard and fights Tom again while Darcy drives the boat.

A para-sail is released, taking Tom and Sean into the air. Tom zips down the line to the boat deck. He and Darcy cut the line, sending the para-sail loose into the helicopter's rotors, which kills both Sean and Harriet.

Back on the beach, as authorities take the remaining pirates into custody, Tom and Darcy get married.
