Story so far:

Having negotiated their first contract, the newly formed SAP are en route to Grimbsy-Under-Sea to meet the manager of Biogate Inc who suspects some of their proprietary research has been stolen.

 

Halfway to their destination, their submarine appears to malfunction and crashes to the sea bed. The team are trying to repair the submarine and have found their way into the cockpit where they discover two crew members are dead. One is still alive, though unconscious.
