4 would be astronauts spend 400 days in a land locked space simulator to test the psychological effects of deep space travel but, when something goes terribly wrong and they are forced to leave the simulation, they discover that everything on earth has changed. Is this real or is the simulation on a higher level than they could have ever imagined?
Unfortunately the movie 400 Days is not yet available on HBO Max.
