Flatliners (2017)

Courtney is a medical student who is obsessed with the afterlife. She invites her classmates, Jamie and Sophia, to join her in an experiment, in an unused hospital room: using defibrillation to stop her heart for sixty seconds while recording her brain. She assures them they would not be held responsible for any accidents. Sophia is against this, but Jamie does it anyway. After sixty seconds, they are unable to revive her until a fellow student, Ray, steps in to help. Marlo, another medical student, arrives and learns of the experiment.

Courtney begins to recall experiences about increased intelligence and euphoria. Envious, Jamie flatlines, and has a disturbing near-death experience as he meets his ex-girlfriend. Marlo and Sophia follow suit, increasing the duration of time they are down. During Sophia's turn they are nearly caught and flee the hospital.

The visions experienced by those who flatlined are: Courtney sees her sister Tessa, who died in a car crash Courtney caused; Jamie sees the baby he begged his ex-girlfriend to abort; Marlo sees a patient named Cyrus, who died when she accidentally mixed up his medication; and Sophia sees Irina, whose life she ruined out of spite, allowing Sophia to become valedictorian. Everyone keeps their visions to their individual selves.

Courtney, traumatized by her visions, records a message apologizing and admitting that her interest in flatlining was due to the death of her sister, not for scientific discovery. She dies having been pushed off a fire escape by the ghost of her sister. The others are devastated. They think they may be implicated if their experiments are discovered. They attempt to clean Courtney's apartment of all evidence. Marlo goes to the morgue to find Courtney's phone, where she is disturbed by more visions.

On his boat, Jamie again hears the cries of a baby and a woman weeping. He falls out of his boat and swims to the dock where a figure stabs his hand.

Courtney's recording discloses they all had similar visions. They admit the mistakes they made and come to the conclusion that their haunting experiences are hallucinations owing to guilt from their sins, not the paranormal. The only one who did not flatline, Ray, initially disbelieves what is happening.

Sophia's apology to Irina is accepted. Jamie discovers his ex-girlfriend has kept their baby and pledges to provide for his son. Ray and Marlo get into a fight when he uncovers her attempt at hiding Cyrus' cause of death and she refuses to confess. Marlo hallucinates being suffocated while driving and crashes her car. Tired of being haunted by her hallucinations, Marlo flatlines on her own in the hope of asking Cyrus for forgiveness. She sees Courtney, who tells Marlo that she needs to forgive herself. Ray, Sophia and Jamie arrive to resuscitate Marlo.

Marlo confesses to the Dean and is held on probation. Marlo, Ray, Sophia and Jamie meet to reminisce about Courtney.
