The Hammersley comes to the rescue of a sinking yacht, barely in time to prevent the couple aboard from drowning in it. The man, Brad, also strains his ankle in a weird fall aboard and soon dies from mysterious cramps. His partner Jilla is already gone, invited with key to stay at Bombers's home, when the autopsy reveals Brad died from a fatal overdose as 'drug mule' and was gutted aboard. Jilla, the only suspect, accidentally switched her bag with that of Spider, who is in hospital to have his accidentally knife-wounded hand treated. Campbell Fulton, who runs an aquarium shop, sees trough Nav's lame ploy to snoop and warns her at the edge of a shark pool. Jilla's gang resorts to desperate measures.
