The film begins with a person committing suicide by jumping from a building narrated by Ramirez (Jacob Vargas) who mentions that his mother tells him stories of the Devil roaming the earth, and it always begins with a suicide. Detective Bowden (Chris Messina) is called to the scene to aid in the investigation. Bowden is a recovering alcoholic devastated by the death of his wife and child in a hit-and-run accident by a driver who was never caught. As this is happening, five strangers, who have committed various crimes in the past, step onto an elevator located within the same building where the suicide has taken place.
The five strangers include Ben (Bokeem Woodbine), a temp security guard with a violent past; an elderly woman (Jenny O’Hara) who is a compulsive thief; Vince (Geoffrey Arend), a mattress salesman who moonlights as a con artist; Tony (Logan Marshall-Green), a former mechanic who served in the U.S. military during the War in Afghanistan who is now seeking employment within the building; and Sarah (Bojana Novakovic), a greed encompassed heiress meeting with her lawyer in the building.
Strange things start to occur beginning with the elevator becoming stuck between floors. Then, after the lights go out, Sarah is inexplicably wounded on her back. The remaining occupants of the elevator quickly begin to suspect Vince of having committed the assault. Slowly, one by one, the five strangers start to die. First, Vince is killed by a shard of glass from a mirror which slices his jugular vein. Detective Bowden, sensing a connection between this and the man who earlier committed suicide in the same building, is compelled to further investigate. Checking the building’s guest log, Bowden finds that only four people have missed their scheduled appointments that day: Sarah, Vince, Ben, and Janecowski. The investigators misinterpret the latter as Jane Cowski and assume this is the old womans name, leaving Bowden suspicious of Tony who appears to be the only undocumented occupant.
