One of the great onscreen romantic pairings, Alan Ladd and Veronica Lake, ended with this romantic adventure film, their fourth cinematic collaboration. In Shanghai after WWII, veteran pilots Larry Briggs (Ladd) and Pete Rocco (Wally Cassell) are dismayed when informed that friend Mike Perry (Douglas Dick) will soon die of a terminal illness. Larry and Pete decide to keep the tragic news from Mike and spend the next weeks showing him a high time. To finance the festivities, they accept an offer of $10,000 from unscrupulous war profiteer Zlex Maris (Morris Carnovsky) in exchange for a flight to Vietnam. When departure time arrives, Maris shows up with the police in hot pursuit, so the buddies take off with his secretary, Susan Neaves (Lake), whose briefcase contains Maris' earnings -- $500,000. En route to Saigon, however, the crew crash-lands in an Asian jungle. As they make their way back to civilization with a detective (Luther Adler) tailing them, Mike develops feelings for Susan, who plays along at Larry's urging. Susan, however, is actually falling for Larry and vice versa.
