Paul (Jason Lee) is about to marry Karen (Selma Blair), by all accounts the perfect woman. Yet at his bachelor party, he finds himself smitten by a clumsy Tiki-girl, Becky (Julia Stiles), and wakes up hung over the next morning only to find her in his bed. Guilt-stricken by the situation, he would like to tell Karen what he did. The only problem is that he doesn't remember what happened. As Paul tries to find out the truth, the discovery that Becky is actually his fiancée's cousin is all the more shocking. And to make matters even worse, Becky's psychotic ex-boyfriend, Ray (Lochlyn Munro), is a crooked cop who is determined to get Paul out of Becky's life by any means necessary. Ultimately, Paul must decide whether to marry Karen and take the logical next step, or to take a cue from Becky and embrace his more spontaneous and creative side. This slightly quirky romantic comedy from director Chris Koch (SNOW DAY) features a healthy dose of slapstick from Lee, who is well-suited for the role. James Brolin appears as Karen's macho father, and Julie Hagerty plays Paul's mildly flaky mother.
