Church discovers a note from Sheila and Lopez confirming that they have started a robot army. At the Red Base, Sarge unveils the two new robots; one contains a microphone to spy on the Blues, and the other contains a bomb. The Reds and the Blues meet in the center of the gulch to execute the exchange. Sheila and Lopez also arrive to conquer the Blues; Lopez becomes angry at seeing new robots brought into the conflict, and rushes forward to attack. A tense Mexican standoff results, and Sarge tries to call an air strike. However, due to crossed communication channels, Tucker intercepts his message, and realizes that Vic is apparently working for both Red and Blue Commands. While Church possesses one of the robots, Tucker tries to alert everyone that Red and Blue are the same, but is hit by a rocket before anyone can understand him. His attacker is apparently Doc, possessed by O'Malley, who flies around on the hovercraft, firing rockets at will. In the ensuing chaos, O'Malley takes Lopez as a hostage, announces his intention to conquer the universe, and disappears through the Red Team's teleporter. The Reds and Blues call a temporary truce to pursue Doc, whom the Blues need to heal Tucker, and to retrieve Lopez, whom the Reds need for the plans his memory contains. Donut, Sheila, Tucker, and one of the robots remain behind in the gulch while everyone else follows through the teleporter. Tex soon surfaces in the remaining robot body. Unfortunately, due to a teleporter malfunction, the pursuing Reds and Blues end up separated and scattered across different places. Simmons ends up in a huge area full of teleporters, Church and Grif end up captured by Max Gain, a member of the Red team in Sidewinder, and Sarge and Caboose appear in the stream in Battle Creek.

Future Church watches Tex, Donut and Tucker leave for Sidewinder, and soon follows them. He talks first to Sheila before leaving for Sidewinder, asking her to do him an inaudible favor. Once at Sidewinder, Future Church finds his past self and Grif in prison, and opens their cell by pressing a button in another room. He attempts to contact Tex, who is currently being held by O'Malley and Wyoming, before another Church approaches him. This new Church claims that he fails to stop the bomb, and gets blown back in time again, only to return to Sidewinder. He then tells Future Church to "meet us at the top of the ramp." The bomb goes off, and Future Church is sent back in time. As seen in Episode 50, as soon as Church is teleported by Gary to Blood Gulch, Future Church arrives and asks to be sent to Sidewinder because he screwed everything up. Just then, more Churches arrive, each having been unsuccessful to stop the bomb, and thus sent back in time to Gary. These Churches all meet in Sidewinder, and explain to the newest Church how their various plans failed. It is determined that whichever Church did each one of these plans already must be the successful Church, since he isn't sent back in time again. This Church gives up on trying to correct everything, instead freeing Tex, and rejoining the Blood Gulch soldiers before the explosion, thus being sent into the future. Church emerges at O'Malley's base, just in time to ask Gary, who remains there, to stop the bomb from detonating. He then prepares to explain the events he went through.
