Ritchie Spencer and his friends have a problem. They are the only four members of their fraternity, and they are all graduating. They must find a way to bring in more members before they leave, and dodge their way around the rival jock fraternity.

Five years after throwing a killer party and stealing Muffin away from alpha-male Zeta frat member Bud, head party nerd Ritchie is married (to Muffin!) and runs a detective agency.
