The festivities are orchestrated by the best man, who aims to throw an unforgettable bachelor party, while the bridesmaids plan a similarly wild bachelorette evening. However, differing agendas and personalities quickly turn the celebrations into a chaotic cacophony. One couple struggles with trust issues, another faces the pressures of impending parenthood, and yet another grapples with commitment fears.
