Buster (Rami Malek) works night shifts at a hotel to provide for his wife and daughter. He does not plan on doing that for the rest of his life, so they live as cheaply as possible to save money to finally be free.
One night Buster meets a drifter with wild conspiracy theories and he starts to believe in them. This and his lack of sleep starts to cause a growing paranoia.
We see Buster in two phases of his life, as the trying-to-do-good father and as a derailed drifter. The film slowly explains how that came about.
An alright film.
