Jeopardy (1953)

Helen and Doug Silwin go on a holiday to Mexico with their young son Bobby. They spend a night in Tijuana and then gas up in Ensenada before they begin the long drive to the very tip of the Baja peninsula. Doug wants to take his family to a special beach he and an old army buddy once stayed at. The countryside is desolate and they only people they meet are at a police road block but they get little information and are soon on their way. They get to the beach safely but in a strange turn of events, Doug finds himself trapped when part of the pier collapses and he is unable to free his foot. With the tide coming in, Helen sets off to find some help and thinks she's found it when she runs into an American, Lawson. She soon realizes that Lawson is on the run from the law and that he will demand a high price from her to help them.
