Lying in sickbay, Commander Chakotay is struggling to communicate with aliens with whom he is linked. He flashes back to events that brought him there. He is in a boxing holodeck simulation when he is knocked out. Shortly after, Voyager is pulled into chaotic space, where the laws of physics are in flux. Shear forces may destroy the ship unless they redesign their sensors to work inside the disturbance.
Chakotay slips in and out of reality, returning to the boxing match again and again. His mind had latched onto the boxing holo-program he had recently used. The Doctor concludes that Chakotay has a genetic marker for a cognitive disorder. Chakotay then insists to take a vision quest. Attached to a cortical monitor, he suddenly finds the aliens communicating through him. They tell him Voyager entered the space through a trimetric fracture and they must alter their warp field to escape.
During a boxing match, with the opponent, Kid Chaos, Chakotay begins to piece together the instructions he is receiving. His fear of losing control almost causes him to block out the voices, but the Doctor convinces him he must give into it. In reality, Chakotay carries out the directions on the Bridge as the graviton shear quickly increases. Suddenly, the ship's sensors set the correct course and the ship is returned to normal space.
After the ship is safe, Chakotay is given some time off, which he uses to further continue his boxing holo-program.
