Synopsis by Hal Erickson
Called up for two weeks' service as a Naval reserve Lieutenant Commander, Mr. Mooney (Gale Gordon) is reluctantly committed to be first officer on the submarine manned by Commander Moore (Robert Carson)--and it's all because of Lucy's well-meaning interference. But wait--there's more! Obliged to deliver an important message to Mooney, Lucy (Lucille Ball) is forced to disguise herself as a male sailor. A literally explosive climax caps this waterlogged misadventure, in which future Lucy Show semi-regular Roy Roberts (Mr. Cheever) appears as an admiral.
