Courtney proposes an audacious and dangerous experiment: she intends to deliberately stop her heart to record the brain activity that occurs post-mortem. Despite her friends' initial hesitation, they consent to participate in her risky endeavor, which quickly spirals into chaos. The dark allure of knowing what lies beyond death becomes too strong to resist, leading them to undertake the potentially fatal experiment that tests the limits of their bonds and their sanity.
