Terror in a Texas Town

When Swedish-American whaler George Hansen returns to his Texas hometown after 20 years at sea, he's shocked to learn that his father was murdered just two days prior. The feckless local sheriff won't do anything about it, so George investigates on his own and discovers that an oil speculator had his father killed for refusing to sell his land at an unfair price. Enraged, and armed only with a speargun, George goes looking for justice.
