In the Philippines during World War II, an American major tries to move a guerrilla unit and group of American refugees to the coast, so they can be rescued by submarine, all the while trying to avoid capture by the occupying Japanese forces. Leopoldo Salcedo played the handsome Filipino guerrilla leader who is in love with a stranded American girl Kathy (Diane Jergens).
The Philippines were overrun by the Japanese during WW2, and had to resort to guerilla fighting until General Douglas MacArthur made his famous return. The Philippines was liberated in 1945.
This movie also features the main character, Ramon, with Mr. Hughes and his daughter Katherine, both Americans, hiding in a cave and discovered by a primitive band of locals. These are presumed to be the Aeta people, thought to be the original people of the islands. The Aeta are smaller and darker than most Filipinos, and possess dark curly hair that made the Spanish, when they invaded in the 1500s, label them as "negritos".
