A Mexican honeymoon turns into a nightmare when Laura Needham (Eileen O'Neill), the young wife of tourist Mark Needham (Peter Graves), is murdered. The police suspect that the crime was committed by wealthy businessman Theodore Bond (Albert Salmi), but they lack the evidence to make an arrest. Taking matters into his own hands, Mark vows to bring the elusive Bond to justice -- but it is another tourist couple, Louise and Alex Trevor (Sarah Marshall, Ed Nelson), who finish what Mark has started.
