This film is set in southern California in the period shortly after California became part of the US. American settlers and the US government discriminated against the Mexican landowners and frequently took their land by force or legal skullduggery. This film focuses on wealthy Latino ranchers whose land and wealth are at risk. They decide to misdirect a US government ship carrying gold so that it will be wrecked and they can take the gold. To prevent themselves from being caught, they plan to massacre the local Chumash Indians. The hero is the now estranged adoptive son, a master swordsman (trained in Japan!) and gunfighter, who tries to prevent this while still saving his family. The plot reflects the sad history of double colonialism in California, the scenery is gorgeous (as is love-interest Barbara Carrera), and the action exciting.
