During WWII, a drunken Pharmacist's Mate must operate on the injured captain of his ship after an air attack. The chief medical officer on a near-by ship assists the terrified young man dealing with his own demons having been detained in the brig for his drinking problems to perform the operation on the critical captain by providing instructions over the ship's radio. Things turn worse at a crucial moment during the operation when the ship the young man is in contact with comes under fire. Unaware that this has happened until the Lt. Commander informs him that it's impossible he communicated with the Medical Doctor of the nearby ship because he was killed during the bombing, but the first mate says that's impossible since he received the directions across the wires.
