In 1769, the expedition of Captain Gaspar de Portola Anthony Quinn to California is in search of fabled cities of gold. Its religious advisor, peaceloving missionary Father Junipero Serra Michael Rennie, wishes to establish good relations with the local natives and to build a string of missions, beginning at San Diego Bay. He is unexpectedly aided when Portolas prideful second in command, Lt. Jose Mendoza Richard Egan, saves the life of Matuwir Jeffrey Hunter, the son of the local chief. But when a supply ship fails to appear and the expedition prepares to return to Mexico a failure, Mendoza betrays Matuwirs sister Ula Rita Moreno, whom he has seduced, resulting in her accidental death by a fall from a cliff. Threatened with annihilation by Matuwirs warriors when both Portola and Father Serra refuse to turn him over, Mendoza prevents war by surrendering himself to Matuwir for torture and execution. As the Spaniards begin to leave, the supply ship appears in the bay as if by a miracle.
