Unfortunately he overdoes the dosage and Duncan falls into the ship's swimming pool, arriving soaking wet at the captain's cocktail party. The captain sacks him and in revenge Duncan tells American passenger Mrs. Tranmere that Loftus loves to sing, so she asks him. Ultimately Loftus reinstates Duncan because the party was a huge success, due to his singing.

Dick and Duncan are both smitten by the lovely Anna-Maria, a glamorous Austrian passenger. Dick gets to bandage her finger but Duncan,as the senior officer, takes over and keeps Dick away from her by forcing him to make animal noises in a talent contest. Anna-Maria is persuaded to enter a beauty pageant which she wins. However she has also attracted the attentions of the captain and when Duncan goes to her cabin, finds Loftus there in a compromising position.
