Synopsis:
The Blackhawks are dispatched to a remote island to recover three inventions of a dying scientist. On the way to the island, they encounter Killer Shark and Zinda. Blackhawk is forced to shoot them down, where they plummet to their apparent deaths.

The Blackhawks then arrive on the island and begin collecting the inventions. Each device is guarded by a special traps which the team must first defuse. While recovering the second invention, Killer Shark steals the first, an experimental missile.

Learning that the crooks are still alive, Blackhawk has Stan and Olad guard the second invention while the others find the third. Zinda surprises the team and gets to the invention first, while Killer Shark takes the second invention from Olaf and Stan.

Blackhawk is left in the center of an active volcano, but he manages to escape. He is able to take over Killer Shark's jet and capture his opponent. Two of the inventions are recovered while the third falls into the volcano where it is destroyed.
