Injured U.S. soldier Miles Willis awakens to discover he is trapped in a mysterious cube armed only with his combat gear. As Miles begins to question his sanity, he finds a lifeline – a voice on the other end of his satellite phone who claims to be a prisoner in a similar space. As the walls close in, these two strangers must put their heads together if they are to outwit their captors and unlock this deadly puzzle.
