Pirates take over a lighthouse on a rocky island. They then execute a devious plan to cause ships to run aground, pillaging their wrecks. A lone member of the lighthouse crew survives, and he deperately fights their plot. A shipwrecked maiden that avoids the pirates slaughter soon complicates the situation.
