005, 006 and 007 are tracking an electronic signal when they suddenly have problems with their aircraft and have a crash landing on an unmanned island. In their hunt for food they find a deserted BG base, which is guarded by a robot that was left alone. The robot thinks they are its new masters and the heroes become friends with this robotic creation. He brings them food and starts up the base again so they can search for loose parts for their airplane. The security alarm is activated and defense robots attack them. Their robot friend sacrifices itself to save 006's life and walks with its remaining powers under enemy fire to the timer for the base bomb. The robot deactivates it before falling down. This leads to 006 becoming a very close friend to the robot and 006 manages to save his new friend's life. Searching for his lost friends, 009 finally finds the secret island. Chang gives a sad farewell before he has to leave the island for new adventures.
