Rocky (Jane Levy), Alex (Dylan Minnette) and Moni (Daniel Zovatto) are three habitual thieves who are good at "breaking into empty houses". This time, they set their sights on a blind veteran. The veteran's daughter had just died in a car accident, and the veteran received a huge amount of compensation. Rocky hoped to take the money, wash his hands, and take his daughter away. The three sneaked into the veteran's haunted old house in Detroit, but unexpectedly opened the door to hell. The veteran has a higher sense of smell and hearing than ordinary people, as well as extremely agile action, and soon discovered the whereabouts of the three uninvited guests. Under his gun, Rocky and his group were like turtles in a jar, with nowhere to escape. In the tense and fierce pursuit, Rocky and Alex accidentally fell into the basement, but discovered a terrible secret.
