When Detective Brett Hopper woke up this morning, he thought it was a normal day, a day like any other one, but he rapidly find out that he is accused of killing Assistant District Attorney Alberto Garza. Even after offering a solid alibi, no one is believing him. The next morning, when he wakes up, he finds out that he is reliving the same day and that his loved ones are in danger.

Brett makes the decision to take Rita and try to make a run for it by getting out of town, in an attempt to escape the day. But he soon discovers the disastrous consequences of his rash actions on others.

Hopper learns someone close to him may have been involved in framing him for Garza's murder. Meanwhile, some critical clues are revealed that could assist Hopper in making his nightmarish day finally end.

While trying to find out who framed him, Hopper is starting to figure out what his partner, Andrea, did that caused her disagreement with Internal Affairs.

To prove his innocence, Brett visits the Internal Affairs office, twice, in search of the murder book. During his first visit, things aren't going like he planned but his second time isn't better when he doesn't have any other choice than taking someone hostage.

Hopper tracks down a major player in the conspiracy to frame him for Garza's murder. He also learns he must weigh the consequences of his decisions after he sees the results of his actions affect the day with adverse results.

Hopper unexpectedly meets again with Jared - the guy who bit him in the fifth episode - and finds out that he is not the only one reliving the day over and over again. He also finds out that there was an eye-witness and that he was identified as Garza's murderer, while realizing that he has to deal with very powerful people. He also learns that people that are close to him might know more than they say they do.

Hopper fears that his sister, Jennifer, is mixed up in the plot against him, but he must first visit his mother to find out the connection. He suspects that his late father's involvement in the Contreras murder is at the bottom of it. Meanwhile, Andrea tries to find Fencik and Buchalter's ties to the plot, and Chad meets Buchalter. The meeting doesn't go well.

Hopper struggles to find the connection between Booth, a city counsellor, and Garza. That connection seems to lie in the role Luis Torres, Booth's assistant, has.

After some more research Hopper finally finds out, who the real murderer of Alberto Garza is.

To his disappointment, Hopper wakes up to the same day although the case had been cleared the night before. He decides to take a break for two weeks only to learn the case has become even more mixed up.

Hopper finds out that his girlfriend Rita plays an important role in the whole conspiracy.

Hopper finally breaks the day and sees "tomorrow" only to find out, that the next day brings some more problems with it.
