Synopsis:
The Blackhawks investigate reports of a giant whale attacking ships. They discover the whale is a submersible craft piloted by Killer Shark. The Shark knocks down the Blackhawk jets and captures the team. The team escapes from their captors with the help of Blackie, then they take control of the whale. Killer Shark causes the whale to self-destruct, but the Blackhawks get off in time. Before the Blackhawks can regroup with the Navy, Killer Shark eludes capture.
