Flatliners (2017)

When a bunch of med students get embroiled in the search for life beyond death, they find themselves stopping their own hearts for minutes to get a first-person glimpse - but what starts out as reassurance turns into a nightmare. As it turns out, if you want to tango with death, it'll tango with you, and the students all start having visions from people who have died under their watch. The visions become increasingly more violent and threaten to kill the students - for good. Diego Luna is the only one who doesn't stop his own heart, but he does go shirtless during a post-sex scene, as does James Norton when he takes a shower on a boat.
