Thomas (Robert Morse) had the bad luck to be born the son of a celebrated Navy man. Although he is now an ensign in the Coast Guard, he is sort of a bad-luck magnet. He gets into numerous fender benders and mishaps, at home and on the job. This causes his superior officer (Don Ameche) much grief. Nevertheless, Tom's goofy charm wins him the heart of a woman in the boat business, Kate (Stefanie Powers). Into this mix comes a trio of jewel thieves with a leader named Harry (Phil Silvers). They were headed toward Mexico when the police, chasing them, closed the borders. Trying to hideout at the shoreline, they accidentally dropped their picnic basket full of jewels into the shallow coast waters. Aspiring to draw little attention to themselves, they take turns diving into the water to try and recover their jewelry. But, Thomas becomes suspicious and tries to find out their secret. Can Thomas salvage his reputation with a big bust on the waters? This is a terrific little film, made long ago, but still every bit a winner. Of course, it doesn't hurt to have the talents of Ameche, Morse, Powers, the great Silvers, Wally Cox, and others on screen. They are supremely capable of generating a "boat load" of laughs, haha. The plot is ingenious, too, with several twists, turns and surprises. Although the film does look a bit dated, it still sports nice costumes and lovely scenery, but the cinematography is definitely lacking. What is really strange is that the film, made for families, is truly more for the adults than for children. There is some slapstick, of course, but most of the humor will fly over the heads of the kiddies. Then, too, there is a good deal of women running around in skimpy swimsuits and some celebration of those "happy hours" on board. Nevertheless, do not skip over this little gem. It is quite funny and clever, putting any viewer into a "yuk fest" funk that will last for hours.
