"Shattered" is the 157th episode of the American science fiction television series Star Trek: Voyager, aired on the UPN network. It is the 10th episode of the seventh season.

This series follows the adventures of the Federation starship Voyager, isolated tens of thousands of light-years from home. In this episode, a spatial phenomenon causes the ship to be fractured such that different parts exist at different points in time and Commander Chakotay must fight old adversaries in order to get Voyager restored to normal.

While Commander Chakotay is discussing with Icheb and young Naomi Wildman where to hide a special stash of cider from Neelix, the U.S.S. Voyager is struck by a chronokinetic surge from a rift in space interacting with the ship's warp core. Chakotay is struck with a blast of temporal energy. He gains consciousness in Sick Bay where the Doctor has injected him with a chronoton serum to repair injuries from the temporal blast. As Chakotay talks with the Doctor, he finds the Doctor believes it is several years earlier. Chakotay goes exploring the ship, and discovers that various sections of the ship are experiencing different periods of time, a result of the chronokinetic surge. The chronoton serum enables Chakotay to see and travel between these periods, but not other members of the crew.

He makes his way to the bridge, which is currently set a few days before Voyager was taken to the Delta Quadrant and before he joined the crew. Captain Janeway immediately identifies him as a spy despite his pleas, and ordered to the brig, but en route, they pass through another time period, which Chakotay passes into but not his captors. During his exploration he finds that Engineering has been taken over by Seska and other Kazon, and though captured, he managed to escape due to his ability to travel between these time periods. Chakotay returns to Sick Bay and has the Doctor create more of the chronoton serum, then returns to bridge, injects Janeway with the serum, and takes her to another time period to avoid capture.
