Pai Zhuq Kung Fu School is looking for its next generation of guardians to guard the Dai Shi. Jarrod is furious that he wasn't chosen and accidentally unleashes the Dai Shi. Master Mao sends students as the world's only hope, Theo, Lily, and Casey, to capture Dai Shi. RJ, their new master, comes to save them and help them out by turning them into Power Rangers.
The Rangers don't stand a chance against a huge Mantor. RJ won't teach the Rangers how to channel their Megazord power till they can work together. Camille and Mantor plot to destroy the city for Dai Shi. Theo comes to terms with the fact that Casey, a new student, was chosen to be on the team. The Rangers learn to help each other out and use their Megazord to defeat Mantor.
Casey realizes that Theo and Lily are much more skilled than he is and asks RJ to give him extra training. RJ has Casey do household chores around his loft. Very reluctant, Casey does the work not knowing that he is learning the techniques he will need to defeat Dai Shi's newest monster. Using the same techniques he learned while doing chores for RJ, Casey stands his ground against Buffalord.
The rangers are shocked when Dai Shi reveals himself to them in the body of Jarrod. Dai Shi calls on the 5 poisons to orchestrate the end of the Rangers. After a nightmare of Jarrod getting revenge on Casey, Lily is worried that Casey might be in danger. She puts herself out there and fights Rantipede, the first poison. RJ reminds her that they will only win as a team.
Theo has been the best and fastest learner at everything. His confidence is smashed when he is made a fool in a battle against Gakko. Theo gives up and doesn't see the point in anything. Casey and Lily try to protect the city from the mischievous Gakko as RJ trains Theo. The battle worsens for Casey and Lily. In order to save his friends, Theo must regain his confidence.
Theo struggles with the fact that his duo with Lily has now become a trio. Camille uses Toady's love for Stingerella to get them to work together in order to defeat the rangers. Because of the tension between Casey and Theo, the rangers can't operate the new Claw Canon. Lily confronts them telling Casey that he is needed on the team, and to Theo, that he will always be her best friend.
