Two guys kidnap the wife of a rich man and bury her in a box with 24 hours of oxygen. Tough NYPD Detective Maddy and others get the case. Will they get to her in time?

Having no recollection of how she ended up there, Liz Hansen wakes up from her deep hypnosis in an air-sealed cryogenic unit the size of a coffin. With the oxygen resources steadily depleting, Liz must remain composed to piece together her fragmented memories and reconstruct her opaque identity with the help of M.I.L.O., the pod's state-of-the-art A.I. However, trapped Liz can't move, she can't get out, and her oxygen levels can only last ninety short minutes. Does Liz have a fighting chance of surviving? Is there an escape from this claustrophobic nightmare?
