Saigon 1947

World War II has ended, Major Larry Briggs learns that his friend Captain Mike Perry has only two months to live due to a head injury. To give Mike a memorable send-off, Larry and Sergeant Pete Rocco hatch a plan. For a $10,000 fee, Larry takes a flying job with Alex Maris, a shrewd profiteer. Everything is set when Maris’ secretary, Susan Cleaver, arrives to board the aircraft. Mike falls for Susan, and Larry convinces her to go along, but she has fallen for Larry.

The first flight is interrupted when Maris arrives half an hour late with the police right behind. Larry takes off but is forced to make an emergency landing after both engines fail. After checking into a small hotel, they discover Police Lieutenant Keon shadowing them, convinced they are smugglers.

When Larry sees Mike falling for Susan, he wants the romance to end, and despite her carrying $500,000 for Maris, Larry tells her to leave immediately. When Mike longs for Susan, Larry relents and blackmails her into seeing him or he will turn her into Keon.

Sailing to Saigon on a boat, Larry tricks Keon by stowing the money away into an envelope he mails to himself, and throws off suspicion about Susan.

On reaching Saigon, Larry knows he has fallen in love with Susan even though Mike has proposed to her. At Susan’s hotel, an enraged Maris and his valet Simon hold Larry hostage, demanding the money that has been posted. Sergeant Pete Rocco realizes what’s happening and fights with Simon, but both men fall off a balcony to their deaths.

Susan secretly arranges to retrieve the money from the post office, returning it to Maris. Mike and Larry confront him, but in an exchange of gunfire, Mike and Maris are killed. After Mike’s funeral, Larry and Susan start a new life together.
