Nelson sets up his experimental base in an abandoned building, bringing in the necessary medical equipment. The group, driven by scientific curiosity, agrees to participate in this risky venture, ready to explore uncharted territory.

Nelson flat-lines for one minute, during which he experiences visions of a boy he bullied as a child, Billy Mahoney. Upon reviving, he describes a profound experience, piquing the interest of his classmates in their risky exploration.

Following Nelson, Joe flat-lines with plans to be dead for 90 seconds. In his brief afterlife, he has an erotic sequence, affirming Nelson's claims about the existence of something beyond mortal life.

David, interested in Rachel and seeking to outdo Joe, engages in a bidding war for flat-lining time, ultimately bidding 140 seconds. His experience pits him against visions from his past, particularly haunting memories of a girl he bullied.

Despite David's last-minute trepidation, Rachel flat-lines next, provoking intense concern among the men. The tension escalates as a power failure jeopardizes her revival, but she survives, only to face her own haunting memories.

As Rachel revives, she begins experiencing flashbacks of her father's suicide. The men bond over their respective traumas, sharing their experiences and ultimately leading David to seek redemption by confronting his past.

Determined to make amends, David tracks down Winnie Hicks, the girl he bullied, and apologizes to her. Her acceptance of his apology lifts a heavy burden off David's conscience.

During a cemetery visit to Billy Mahoney's grave, Nelson reveals the dark truth of how he and his friends accidentally caused Billy's death. This revelation burdens the group as they grapple with their past actions.

While alone, Rachel has a powerful encounter with her father's apparition, who apologizes to her. This encounter lifts her guilt regarding his death, providing her with a sense of closure.

Feeling the weight of his unresolved guilt, Nelson decides to flat-line again to seek closure. He calls Rachel, confessing his need to make amends, prompting an urgent race to save him.

Rachel and the others realize Nelson's intentions and attempt to reach him in time. They find Nelson flat-lined after a lengthy attempt to revive him, only to be met with despair as time ticks away.

In his afterlife, a young Nelson finds himself reliving the torment he subjected Billy Mahoney to. The cycle of guilt culminates when young Nelson falls, transforming into his older self, signaling his inner turmoil.

In a desperate attempt, David gives Nelson one last shock, resulting in a miraculous revival. As Nelson comes to, he humorously remarks, 'Today wasn't a good day to die,' indicating a newfound appreciation for life.
