Synopsis:
The Blackhawks split their forces to track down the leader of the criminal organization known as Sword. Unknown to the team, Sword is expecting them. The team walks into an ambush and one of their members is captured and brainwashed. The captured team member is then sent to capture Blackhawk himself with no memory of his own identity. After capturing Blackhawk, the captured team member is revealed as Chop-Chop. However, in the process of capturing his boss, Chop-Chop's memory is restored. He turns against his captors, rescues Blackhawk, and helps bring down Sword.
