Harry Kim is aboard a shuttlecraft as it is shaking violently. As he contacts "Voyager", Captain Janeway attempts to beam him out, and he awakens on Earth in  San Francisco next to his girlfriend, Libby, whom he had dearly missed. The date is the same as he remembered, but his life is completely different: Harry retains his memories of his time on "Voyager", yet there is no evidence he was ever aboard. Kim finds he was denied a posting on "Voyager" and then took an assignment working at the shuttlecraft development center at Starfleet Headquarters. After he leaves a briefing with staff admirals because of "sickness", he looks for any explanation for his current situation. Harry uses his knowledge of "Voyager"s security codes to obtain classified information on  his ship. Kim realizes he has somehow swapped places with his friend Daniel Byrd. While skimming through the crew manifest, Kim notices Tom Paris is not listed as part of "Voyager"s crew either. He learns Paris now lives in Marseilles, France, after his parole, and goes there to try to enlist his help in figuring out what happened. Paris tells Kim that he lost his "advisor's" spot on "Voyager" after Odo threw him in the brig for getting into a fight with a Ferengi prior to "Voyager"s departure — a fight Kim prevented in . Upon his return to San Francisco , Kim is apprehended by security and taken to Starfleet Headquarters for questioning because of his unauthorized access to restricted files and his recent association with Paris. Kim is suspected of being a Maquis spy and is fitted with a security anklet to track his movements. He discovers that a shuttlecraft accident caused him to fall into a time-stream and enter a timeline where he was never a part of "Voyager"s crew. A time-stream alien tells Kim that if he recreates the conditions of the accident precisely, he might get back to his own reality, but there is considerable  risk. Harry tries to tamper with his security anklet, but sets off the tampering alarm, which alerts Starfleet. Paris comes to Kim's aid and rescues him. They steal a shuttlecraft and recreate the accident moments before they are destroyed. Immediately Kim is returned to his own reality and is happy to find everything is as he remembers it.
