Two couples find themselves unwilling guinea pigs in a scientific experiment with supernatural undertones in this Christian-themed horror movie that asks what frightening forces lurk just beyond the edge of our consciousness. Upon coming to in a darkened operation room, Lisa Williams (Hilary Kennedy) and Debra Reynolds (Gwendolynn Murphy) are shocked to find Lisa's boyfriend David (Manuel Velazquez) and Debra's husband Tony (D.C. Lee) handcuffed to a pair of nearby operating tables. There is no exit from the room, no one will reply to the women's repeated cries for help, and two unconscious men lie motionless on nearby beds. Neither Lisa nor Debra can recall how they ended up in this place, but as David and Tony begin to regain conscience it quickly becomes clear that they are being forced to take part in some sinister scientific experiment. Now, as the women try desperately to find a way out of their predicament, the men begin to experience a profoundly disturbing change. According to them, there is something unseen and thoroughly evil permeating the air in this room, something waiting for the perfect moment to cross into their reality and strike. With each minute that passes the men seem to become more acutely aware of this diabolical presence, yet the women remain skeptical. It's only a matter of time before this unseen evil manifests itself in our reality, and the longer it takes the women to solve the mystery, the more powerful it will be when it finally arrives.
