Jerry, who is taking life easy in the park, is attracted by a scene between a mother and her baby. Jerry watches the happy woman fondling her child, and as he reflects over his past follies he pictures the day when he, too, will have a wife and a little child to love. Weary at heart, he goes to another bench and sits beside a sleeping tramp, where he, too, is soon fast asleep. He dreams that he is married and that he is the proud father of a family. As he caresses his baby and wife he awakens to find himself kissing the dusty tramp and a fight starts. The police hear the rumpus and as they start after Jerry, he runs away and takes refuge in a tool house near some construction work. The foreman of the work sees Jerry go into the house and quickly follows him. He ejects Jerry and warns him to keep away from the place. The foreman puts dynamite in the little storehouse for safe keeping until the following day, and as he walks away he drops the key of the shack, an incident which Jerry observes from his hiding place. Jerry gains possession of the key and enters the house, ignorant of the fact that it contains explosives. Seeing the police coming, Jerry proceeds to walk away with the house. Down the road a big auto truck is approaching, loaded with picnickers, consisting of policemen and their families and sweethearts. Jerry tries to get out of the way with the shack he is carrying, but unable to do so there is a collision, the explosives are set off and Jerry is sent flying through space. When he lands he is captured and handcuffed to the wheel of the truck. The merry picnickers go in swimming, but one of the women takes pity on Jerry and releases him. He meets four tramps, old friends, and they have a joyous reunion. Jerry and his friends spy the policemen's uniforms which were discarded for bathing suits when they went into the water, and no time is lost in appropriating them. The tramps and Jerry leave their discarded clothing behind and when the cops discover what has happened they rush from the water only to see Jerry and his cronies speeding away in the auto truck. The cops don the tramps' clothing and give chase only to run into the hands of the local sheriff, who mistakes them for tramps he is looking for. Jerry and party see the incident, understand the situation and hurry to the sheriff's aid and help him to take the enraged police to the lockup. The cops protest in vain and while they argue with the sheriff and his men, Jerry and his party motor off to a secluded spot, open the lunch baskets and enjoy their repast while the picture fades out.
