You're in the Navy Now

At Naval Station Norfolk in the opening months of World War II, Lieutenant (navy) John W. Harkness (Cooper), a newly commissioned officer, bids goodbye to wife Ellie (Jane Greer) and reports aboard the ''PC-1168'' unaware that his civilian background in engineering and his Rutgers University education has elected him, by means of a hole punched in an IBM card, to head a secret project and command the ship. The Navy has installed a steam engine and an experimental evaporator-Condenser (heat transfer) in the ship to test its feasibility in Patrol boat and has assigned Harkness to conduct the Sea trial.
