In the distant future, Rigby leads a rebellion squadrent (consisting of Benson, Skips, Hi-Five Ghost, Muscle Man, and Pops) against an evil cyborg named Mr. Ross and his army when he is erasing time. When Rigby and his team reach Ross himself, he reveals himself to be in possession of a weapon, the future version of Mordecai, who is a cyborg himself and has discovered a transgression Rigby did to him in the past and attempts to kill him. When the team gets incapacitated, Benson sacrifices himself in order for Rigby to get to a space ship/time-machine to head to the past to stop the chaos. Just as Rigby is about to travel back in time, Mordecai shows up and shoots Rigby when he hits the time travel button.
In the present, Mordecai and Rigby barely keep themselves from being fired when they run late for work. When the space ship from the future shows up and crashes into the ground, future Rigby appears and tells the employees that when Mordecai and Rigby were in high school, they created a time machine that backfired, but created a "Timenado", a tornado with the ability to travel through space and time.They later got expelled for blowing up the science lab. Furthermore, the future Rigby reveals that Mordecai shot him, shocking the park residences that Mordecai and Rigby have receded their friendship. Before dying, future Rigby tells present Rigby that he must reveal a secret that might lose Mordecai in order to save the universe. When questioned about the details, Mordecai explains that they created the time machine because Rigby got into their dream college, College University, but Mordecai didn't. After the unfortunate ploy, Mr Ross, their science teacher/volleyball coach at the time, was held responsible and sent to prison. Benson tries to convince everyone that the whole thing is a hoax, until Muscle Man finds a plasma shotgun and accidentally destroys Benson's car with it. After deliberating, the employees decide they need to use the ship to go to the past and stop the end of the universe.
The group manage to get to the past (6 years in to be exact) but wind up damaging the engines in the process. Skips, Muscle Man and High Five Ghost stay behind to fix the ship while Benson and Pops follow Mordecai and Rigby in finding the time machine. They succeed in slipping in but are forced to split up when they confronted by the volleyball team. With no other options, Mordecai and Rigby are forced to get help from their past selves, who have access to the science lab because Mr Ross, who was feuding with Rigby after his antics cost the team the championship, was forced by Principal Dean to allow Rigby to do an extra credit assignment in order to pass. The extra credit assignment was the time machine Mr. Ross was creating. He was creating it for two reasons: go back in time and win the volleyball state championship and to "get revenge". After successfully convincing past Rigby to create a model volcano instead, the past selves leave the lab, giving the present pair enough time to destroy the time machine. Pops and Benson arrive late to the carnage, all beaten and bruised after their volleyball jock encounter.
The group, assuming the work was over, head back to spaceship/time machine only to find the repairs stalled due to an encounter with Muscle Man and High Five Ghost's past selves. Complicating matters further is that temporal ruptures begin appearing just as the repairs are finished. Rigby, who had slipped away earlier, alerts them to the fact that past Mordecai and Rigby are heading to the high school to finish a second time machine Mr Ross planted. The employees race back to the science lab but are quickly incapacitated by Mr Ross and future Mordecai, allowing past Mordecai and Rigby to botch the time machine and create the Timenado. Mr Ross then forces Rigby to admit the truth: he never got into College U but Mordecai did and he faked Mordecai's rejection letter in order to maintain their friendship. Mr Ross then tries to kill Mordecai in the confusion, but future Mordecai intervenes, taking a heavy wound and forcing Mr Ross to retreat.
Upset over the duplicity, Mordecai angrily ends his friendship with Rigby, forcing Rigby to run off with the spaceship/ time machine. Before dying, future Mordecai gives his present version his ship (which is also a time machine) and tells him to patch things up, saying what Rigby did was no excuse to side with Ross. As the group tries to rebound, a distress call from future Gene the Vending Machine prompts them to help out. Meanwhile, after a failed suicide attempt to drive into the sun, Rigby encounters Father Time, who is falling apart due to the Timenado, and is convinced to apologize to Mordecai. Rigby heads to the future races back to the Timenado but gets intercepted along with Mordecai by Mr Ross at the crystal core. With Techmo's help, the duo manage to decapitate Ross and, after Rigby and Mordecai repair their friendship, destroying the Timenado. They later convince past Rigby to apologize to past Mr Ross before he's arrested, thus ending the issues between them and altering the future.
Back in the present, Mordecai and Rigby agree that, despite how cool their future selves turned out, they won't let their friendship degrade to trying to kill each other, thus erasing their future selves from the timeline. The next day, as Benson catches them away from the park, the pair race back in the spaceship/ time machine with Rigby saying they'll "never be late again".
