Mild-mannered Dr. Tommy Oliver barely escapes the island alive and becomes a high school teacher a couple years later. Among his students are three kids who come from different worlds. Conner is a cocky soccer player who is very popular jock. Ethan is a computer whiz who dreams of being the next Bill Gates. Kira is the lead singer of her band and has plenty of attitude. The three end up getting detention with Dr. Oliver who takes them to a museum. He tells them what he wants them to do to get out of detention while he goes to get information on the museum.

Dr. Oliver explains the significance of the gems to a bewildered Conner and Ethan and takes them along with him to save Kira. Kira finds herself in a lab of sorts and meets a strange reptilian creature who demands the gems. She tells him where they are and is turned over to Elsa and Zeltrax who are ordered to destroy her.

Zeltrax feels that the best creature to destroy the Rangers can only come from him ; he creates Golden Rod who calls him "father". He immediately goes after Dr. Oliver on Zeltrax's orders.
