Story follows Tim, a recent divorcé who learns that his ex-wife Ashley is dating a new man. Still madly in love, and deeply in denial, Tim tracks her new boyfriend, Andy, to a masculinity-themed sleepaway camp, only to discover that Andy is the camp’s five-time champion and current holder of the coveted Manly Cup (a trophy awarded to the camper who best demonstrates his modern manliness by competing in a series of “woke” athletic events such as Vulneraball and the Emotional Obstacle Course). Desperate to prove that Ashley’s new flame can’t hold a candle to her old, a woefully unenlightened Tim enters the competition and begins scheming to take Andy down.
