When a male corpse with the same name as a female neighbor of Tru's comes into the morgue, Tru suspects identity theft. When the day restarts, Tru's investigation takes an unexpected turn that makes it difficult to sort out just who is the victim and who is the criminal. Meanwhile, Tru and Davis piece together some information about Jack, who hasn't been forthcoming about everything in his past.

Tru and Davis remain stunned by the revelation that Jack can relive days like Tru. Excited to have a new partner, Tru teams up with Jack to ensure a doctor's dying wish to help others in his life, but as the day progresses, Tru becomes increasingly suspicious of Jack's intentions. And when Jack attempts to stop Tru from saving an innocent victim, she comes to the startling realization that he isn't her ally but her enemy.

In the first season-finale episode, Tru and Jack--her sworn nemesis--find themselves on a collision course with the stakes as high as they can be after the body of Tru's brother, Harrison, asks for help. Despite his friendship with Harrison, Jack vows to ensure Harrison's death when the day rewinds. Tru struggles to protect her brother, and the game is on as an epic battle of life and death between Tru and Jack is set in motion. But Tru's attempts to save Harrison will lead to the shocking death of someone very close to her.
