In the first episode of a two-part story, the wedding of Jesse (John Stamos) and Becky (Lisa Loughlin) is only a few hours away when Becky's dad (Don Hood) lectures Jesse on the grim responsibilites of matrimony. Faced with the prospect of giving up his wild-and-crazy lifestyle, Jesse decides to take one last fling--and a mighty dangerous one at that. Elsewhere, Michelle (played by the Olsen twins) takes an instant dislike to Becky's nephew Howie (Michael John Nunes).
