Against All Flags (1952)

In 1700, the pirates of Madagascar menace the India trade; British officer Brian Hawke has himself cashiered, flogged, and set adrift to infiltrate the pirate "republic." There, Hawke meets lovely Spitfire Stevens, a pirate captain in her own right, and the sparks begin to fly; but wooing a pirate poses unique problems. Especially after he rescues adoring young Princess Patma from a captured ship. Meanwhile, Hawke's secret mission proceeds to an action-packed climax.
