Five medical students want to find out if there is life after death. They plan to stop one of their hearts for a few seconds, thus simulating death, and then bring the person back to life.
This movie contains 23 potentially triggering events.
A couple of hallucination/flashback scenes with a dog crawling with a broken back early in the movie. About halfway through in a flashback, a tree branch falls on the dog and breaks his back. The kid that fell from the tree died, but it doesn't actually show the dog die, just the injury.
!!SPOILERS!!
Nelson decides the only way he can make amends with his past is to die for it, he flatlines by himself, but the rest of the characters are able to get to him fast enough & bring him back by the end.
There's a couple times where they talk about how they could become brain damaged from the experiment they're conducting & make the whole "vegetable" joke which can be offensive.
I would say some of Nelson's reactions to his past being brought back to him have some similarities to PTSD however I don't think they ever state that's what it is.
Technically speaking, yes. That's the whole plot point is that Nelson wants to do this experiment where he dies for a second and tries to see what happens when you die before the others bring him back. Almost all of the characters try this at some point.
!!SPOILERS!!
they're all brought back after doing this tho
It's quite the opposite actually, the bullies get their past brought back to them and in Nelson's case the victim beats him instead. There are flashbacks to when the characters bullied their victims but nothing where the bully directly beats them up that I can remember.
They all discuss what they think happens after you die, David mentions being an atheist multiple times, other religions and what they think happens after death are discussed.
None of the characters self harm in what would be considered the "traditional sense" but they all frequently intentionally put themselves in a state where they are temporarily brain dead
There's no on screen intense gore but there is some blood from minor injuries, verbal descriptions of surgeries and organs, and cadavers shown in a medical classroom setting
