When an unsuspecting woman stops at a remote gas station in the dead of night, she's made the plaything of a sociopath sniper with a secret vendetta. To survive, she must not only dodge his bullets and fight for her life, but also figure out who wants her dead and why.

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?
