He's got a formula, but hasn't got a clue.

Twenty-five year old Ethan Humphries (Corey Large), "Hump" to his friends, is suffering from a classic case of Peter Pan syndrome. In the seven years since graduating high school, his greatest accomplishment is being able to get into any club in Los Angeles. Supported by wealthy parents, he works out, parties, and brings a different girl home every night. One evening, he gets a call from his inebriated friend, Brad (Luke Kirby), who accidentally spills the beans about their best friend Jeff's (Luke Flynn) wedding - taking place the following weekend. Apparently someone 'forgot' to tell Ethan.

Ethan immediately flies back home to Vancouver and meets up with Jeff, who has become a corporate shill. Jeff has gone so far as to name Stu (Paul Johansson), the brown-nosing Vice President of his advertising firm, his best man. Worst of all, Jeff is marrying Ethan's high school sweetheart, Stephanie (Jennifer O'Dell).

Sliding into regression, Ethan unsuccessfully tries to recreate his high school glory days with his friends, including Sean (Tom Lenk), a well intentioned, but un-hip seventh-year undergrad. Upon discovering that Stu has convinced Jeff not to hang out with his "loser" friends anymore Ethan plans his attack.
