Joes ship was part of a merchant line owned by Daves father. Joe figures that Daves father will reward him for keeping his son safe. Joe gets drunk and rapes the teenage granddaughter. When the girl starts screeming, Dave has no choice but to flee with Joe.They meet a band of armed Filipinos led by Atong and the Englishspeaking woman Sisa. The quickthinking Joe tells the band that if they bring them to Colonel Ryker, an American officer in charge of a guerrilla unit, Ryker will reward them. Ryker tells Dave that the Japanese would probably give him a comfortable existence and might repatriate him to the United States due to his fathers extensive business dealings with Japan. Dave replies that his fathers connections to Japan were from before the war and he would rather fight with the guerrillas. The group join Rykers unit in fighting the Japanese. ........
