After a Near-Death Experience (an "NDE") radically transforms the life of eccentric billionaire Nicholas Sheridan, he recruits a team of other survivors to study the experience. Recreating the conditions that opened the gate to the unknown, they will discover amazing connections, common visions, and dramatic abilities among people who have come back from the dead. But what they haven't bargained for is that the gate opens both ways, and something else has escaped death. Something hunting them... Something hungry.
