An old friend returns to the Rangers’ lives, but the reunion quickly becomes complicated by Rita’s latest scheme. The Rangers are forced to question whether the person returning to Angel Grove can really be trusted, especially as strange events begin taking place around them. Their history with the returning character makes the situation more personal than an ordinary monster attack. As the danger develops, the team must determine what is really happening before Rita can use the situation to divide them or turn someone they care about into another weapon against the Power Rangers.
