After being expelled to a penal colony for adultery our hero falls afoul of a group of pirates who are convinced the original settlement hides a stash of loot.

Curiously land-locked for a pirate opus, there is action a-plenty nevertheless and the odd death by Piranha. Interesting but not totally satisfying Hammer concoction.

Sadly the lesser title in a double bill with The Three Stooges in Orbit in the US!
