After saving the daughter of a ship's captain from drowning in the ocean, Mitch, Stephanie, Summer, C.J., Matt, and even the bumbling maintenance man, Guido, are invited for a cruise on a fabulous ocean liner down the coast of Mexico for a week of relaxation, where Mitch and Stephanie try to rekindle their lost romance. C.J. takes Matt to the ship's casino, and Guido pretends to be a wealthy count to woo a fairly large, wealthy middle-aged widow. Also on the ship is an escaped drug lord, named Nicholas Rogo, with his gang plotting to escape to South America, whom Summer becomes suspicious of his true identity.
