Pat O'Brien makes the casual acquaintance of fellow American Ruth Warrick while on vacation in Mexico City. What Warrick doesn't know is that O'Brien is a treasury agent, out to get expatriate counterfeiters Alan Hale and Edgar Buchanan. What O'Brien doesn't know is that Warrick is also out to get Hale, whom she holds responsible for her father's death. After a lengthy period of cross purposes, hero and heroine team up to catch the crooks. Perilous Holiday puts Pat O'Brien through his standard paces, and provides an offbeat role for the usually aristocratic Ruth Warrick.
