Both Little Ted and Hal have their own plans to disrupt the imminent wedding and they separately call upon Mr. Mac, a world weary swimming coach, to help them out. However, Mr. Mac has a much bigger problem of his own, George. George is the psychotic husband of barmaid Petula, with whom Mr. Mac is having an affair.
