After 18 months in jail, our Trailer Park Boys, Ricky and Julian , head back home to Sunnyvale Trailer Park aiming to get their lives back together again. The problem is that neither Ricky's fiancee Lucy nor his dad Ray will let him back into their homes, and some guy named Cyrus has moved into Julian's trailer, having crowned himself the new "King of the Park."

Fed up with all their demands and complaints, Julian tells everyone that he is leaving the trailer park. Ricky, who has been living in Julian's car on his front lawn, has one week to find a new place to live. Mr. Lahey, the trailer park supervisor, is thrilled to hear of Julian's imminent departure but when he hears that Ricky won't be leaving too, his worst nightmare seems about to come true.

While babysitting both Trinity and Mrs. Peterson's dog, Ricky accidentally gets shot and the dog devours a tray of hash brownies. A vet treats both the dog and Ricky. In order to pay the vet, Ricky and Julian must repossess a lawn tractor owned by a former patient who hasn't paid the vet's bill. The Boys successfully recover the tractor -- but not before Ricky gets shot for the second time that day.

With Ricky's life still a mess, Julian tries to convince him that it's time to marry Lucy. Reluctant at first, Ricky changes his mind when Julian suggests that people will always think that Ricky is gay unless he marries Lucy. Julian's engagement present to Ricky is the '76 New Yorker, which for weeks was up on blocks in his front yard, and is now made operational thanks to a few purloined replacement parts.

Lucy insists that Julian take over the job of organizing her wedding: which is odd since Julian isn't the groom, Ricky is. She wants lots of people and lots of food. The people part will be easy but getting that much food will be difficult on a tight budget. Julian's plan to hit a local grocery store runs into a snag when Ricky unexpectedly shows up in the middle of the heist. Shots are fired. The next day, the cops show up uninvited to the wedding.
