Reality Check (2002)

Four young women and three young men, totally strangers to each other, are sent to an isolated house with the crew members of a reality show to stay living together for three months without any means of communication with the exterior, and in the end, the winner will get a prize of US$ 100,000.00. When the cameraman is found dead in a barn, the group becomes hysterical, since nobody knows who is trustful.

Unfortunately the movie Reality Check is not yet available on HBO Max.
