When a rare, deadly snake is found missing from the Bayport Zoo, all the clues point to Phil Cohen, a friend of the Hardys. Frank and Joe believe that Phil is innocent, even though more snakes are found in Phil's basement. The case turns deadly when a black market lab that extracts venom for sale is discovered.
