After an unnerving pileup on the Los Angeles freeway triggered by a giraffe, Phil, Stu, and Doug find themselves driving the fourth member of their quartet, Alan, to a rehab facility in Arizona. Suddenly they're forced off the road and kidnapped by a gangster who demands they track down an old friend who may have hidden millions in stolen gold. The gang is forced into the mysterious underworld of Tijuana, and then it's back to their old stomping grounds, Las Vegas, where they careen from one crazy escapade to another. Heather Graham returns as a retired stripper, and Melissa McCarthy appears in a role that reveals an entirely new side of Alan.
