No longer having Ranger powers, the former Overdrive Rangers return to their civilian lives. All but Mack, who learns of Thrax's plans to destroy Sentinel Knight, and seeks out the only item capable of doing so, the legendary sword Excelsior. Will he... (more) be doing this alone, or can the call of action prove the adage of "Once a Ranger, always a Ranger" to his former teammates? Meanwhile, their replacements, the team of Returning Rangers, head to Angel Grove to seek out the only being capable of repairing the Morphing Grid: Alpha 6! Even if they succeed, can two combined teams of Power Rangers stop Thrax for good, and permanently break up the Evil Alliance?
