Based on the long-running Power Rangers franchise, five teens from Angel Grove High are granted superpowers and giant robot dinosaur Zords to defend Earth against the alien villain Rita Repulsa. When Repulsa creates an evil Green Power Ranger by brainwashing recent transfer student Tommy, the team is able to free him from her grasp and get him on their side. But with remnants of Repulsa's control still stirring in the back of Tommy's mind, he must confront the fact he may be more of a danger to his new team than a help. This is "Green Ranger: Year One."
