Steve Reeves trades sandals and togas for the frilly, functional outfits common to 17th-century buccaneers in Morgan the Pirate. As the real-life Sir Henry Morgan, Reeves is sold into slavery and forced to work on a Panama plantation. He is purchased by haughty Valerie Lagrange; they fall in love, and as punishment Reeves is condemned to toil in the galley of a Spanish vessel. He leads an escape, overtakes the ship, and establishes himself as a pirate captain. In true Captain Blood fashion, he eventually catches up with his former amour LaGrange, laying waste to most of Panama in the process.
