Dillon's search for Tenaya is put on hold when Scott is in trouble. Scott was shot with a key that allows Shifter to control him. The Rangers do their best to save their leader when they come face to face with Tenaya 15. She has been reprogrammed with one mission: Serve Venjix. Dr. K makes a gun whose shots can make Tenaya susceptible to mind control.
It's time for Ziggy to pay back $5 million he owes Fresno Bob. Tenaya 15 makes a deal with Fresno Bob to give him Ziggy in exchange for a certain case. Instead, she double-crosses Fresno Bob and Ziggy ends up saving him. The Rangers deploy Dr. K's Rail Saber weapon against the latest attack bot. Fresno Bob and Ziggy are now even.
Ziggy accidentally teleports him and Dr. K into a cave! The Rangers need to find out the password to Dr. K's system in order to get them out of the cave. Their failed attempts trigger a time capsule video that Dr. K compiled should they fail to destroy Venjix. The Rangers watch in horror as they figure out what the password might be before its too late.
Venjix's end game is about to reveal itself. Every attack bot has been a calculating step closer to his plan. The city is filled with hybrids just like Dillon. Venjix is going to activate them all and Corinth will be brought down.
The magnetic blast goes off and all electricity goes out in Corinth. Venjix activates the hybrids and the city is his. The Rangers battle an attack bot but they keep losing rangers. Venjix deletes Gem & Gemma. Dillon struggles with being activated as a hybrid. And Ziggy runs to save Dr. K. This may be the end of Corinth.
In order to defeat Venjix, another virus will have to be inserted into his system. The Rangers have Tenaya walk back into enemy lines to insert the virus. Meanwhile the Rangers have to hold up against Venjix in a fight. Dr. K is able to reverse Venjix's deletion of the Gold & Silver Rangers. Reunited, they attack Venjix in his weakened state. Venjix is defeated and the war is over.
