400 Days

Four astronauts – Captain Theo Cooper, Dr. Emily McTier, Bug Kieslowski, and Cole Dvorak – begin a 400-day-long simulation on Earth intended to study the long-term effects of space travel. As their time underground grinds on, the crew begins to deal with extreme psychological effects like paranoia and hallucination. The team discovers that everything on earth has changed after they're forced to leave the simulation, leading them to question what's real and what's part of a higher-level simulation.
