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?
