The concept of the Solar Federation is advanced when space tramp Blaster Martin and his associate Cassidy become involved in its formation to advance the cause of peace.

In this final episode of the series, the Video Ranger reminisces over his rise through the ranks of the Rangers and the many tests he underwent, and his eventual duties as second-in-command aboard the 'Galaxy' with the Captain and the other Rangers.
