Delirium

Tom is recently released from a mental institution and returns to the mansion he has inherited after the death of his parents. Tom is monitored by a tracking device on his ankle for 30 days, with instructions upon his release to 'trust his brain, not his eyes.' This soon proves to be difficult as Tom begins seeing strange things in the house, including his brother who he thinks is in prison. Tom must decipher what is real from what isn't if he is to survive the 30 days.
