A group of con artists impersonates Captain Janeway and the crew of Voyager while pulling scams and marring Starfleet's reputation. The crew must find the imposters soon, or they will be punished for the con artists' crimes.

Former crew member Kes returns to Voyager in a state of rage, blaming Captain Janeway for her past. Using her expanded Ocampan powers in a fit of revenge, she travels through time to betray the crew to the Vidiians, an alien life form that will absorb the crew's internal organs.
