After starting their own detective agency, Nick and Audrey Spitz land a career-making case when their billionaire pal is kidnapped from his wedding.

In the not-so-distant future, all drinking and drugs have been made completely illegal by the government, except for one night a year. High school seniors Griffin, Hags, and Andrew make a pilgrimage to get to the best party in town where all their dreams will come true. They will have to avoid their crazed principal, violent siblings, and the wild animals roaming the streets.

Doug Harris is a loveable but socially awkward groom-to-be with a problem: he has no best man. With less than two weeks to go until he marries the girl of his dreams, Doug is referred to Jimmy Callahan, owner and CEO of Best Man, Inc., a company that provides flattering best men for socially challenged guys in need. What ensues is a hilarious wedding charade as they try to pull off the big con, and an unexpected budding bromance between Doug and his fake best man Jimmy.
