For Sam Durell the action starts with a walk in Rock Creek Park, Washington, D.C.,..and ends in an international race for a trillion-dollar formula. Along the way he picks up a bevy of beautiful hippies. Together they travel from the lush keys of Florida to the Seven Sin Islands of Singapore. There Sam hunts for Madame Hung, an Oriental power broker with a taste for debauchery. That's when the world's most durable secret agent offers himself as a fly to Madame Hung's spider. Then one of the free-loving flower children pulls a super double cross, and Sam is caught by two killers in a torture dungeon--Chinese style.
