The film is about medical students that investigated events after death through submitting to a “flatline” state themselves. The movie claimed that it is possible to defibrillate a person after flatlining. This is a misconception with the explanation based on science particularly the lack of ventricular contraction in an asystole state. Using jumper cables and paddles will not work to resuscitate a person that has flat-lined unless there is already an electrical activity that is present in the heart. Shocking the heart is not viable to resuscitate a patient since cardio activity already stopped.
