Bug is a 2006 psychological horror film directed by William Friedkin, adapting the stage play written by Tracy Letts. Lonely waitress Agnes White (Ashley Judd) has recently escaped her abusive ex-husband Gross (Harry Connick Jr.), and moved into a motel room with lesbian friend R.C. (Lynn Collins). R.C. introduces Agnes to Peter Evans (Michael Shannon), a recently discharged veteran with a muddled history, and the two lonely souls begin an unconventional romance. However, Peter discovers a sudden infestation of mysterious bugs in their hotel room and begins a spiraling descent into conspiracy-fueled paranoia. Peter discloses he was the subject of strange experiments by the government during his service in the war, and the source of the strange infestation. As Agnes begins to feel the same symptoms, the lines between reality and hallucination begin to shift and blur, as the two find themselves either falling into madness or the subject of a strange government cover-up.
