Oliver wants to have a simple, romantic Sunday picnic with Lisa. His afternoon for two turns into an irritating crowd when everyone invites themselves and tags along. Joining the couple are Eb, his girlfriend Linda and her accordion, her parents, Sam Drucker, his date and her sousaphone, Hank Kimball, Linda's Grandpa and some old lady he hit on at the gas station. That night, Oliver and Lisa take refuge in the barn when the crowd shows up at their house.
