Jack Lemmon and Walter Matthau are reunited in this hysterically funny high seas romantic adventure. Gambler and con artist Charlie (Walter Matthau) is desperate to meet single, rich ladies with large bank accounts. When he persuades his lonely widower brother-in-law, Herb (Jack Lemmon), into accompanying him on a pleasure cruise, he neglects to mention that they will be working as dance hosts and masquerading as wealthy bachelors. Much to Herb's chagrin, their accommodations are in the bowels of the high-class ship, and they are forced to work for hilariously tyrannical cruise director, Gil Godwyn (Brent Spiner).
