Kagaku ninja tai Gatchaman

A Galactor traitor steals a secret micro file from a base and gets it to the ISO headquarters. In order to decode the file, Joe goes to the Ongurei Research Institute where they have some special decoding equipment. But there's an electronic transmitter attached to the file. Its signal is detected by Galactor and they proceed to attack Joe. Saved from the critical situation by Ken and the others, Joe hurries towards the research institute again. But a strong headache attacks him. He is blinded and falls towards a valley. "What's happening, this is not supposed to be happening to my body again" he thinks. While losing consciousness, Joe remembers his past, when he found out that his father was a Galactor member, when he died as a result from an old wound he got in his head, and when he was resurrected as a cyborg. Joe is saved by Jun and regains consciousness. The file is safe.
