Trevor Reznik adlı bir makine operatörü uyuma yeteneğini kaybeder. Fakat bu sıradan bir uykusuzluk sendromu değildir. Aşırı yorgunluk ve uykusuzluk yüzünden fiziksel sağlığı ve akli dengesi bozulmaya başlar. Yanında çalışanlar en başta görünüşündeki tuhaflıktan ötürü ondan ürkmeye başlarlar ancak dükkanda onun da karıştığı bir kaza sonucu adamlardan biri kolunu kaybedince adamları karşısına almış olur. Kaza yüzünden Trevor'ı suçlarlar. Artık hem kendisi hem de diğerleri için bir engel haline gelmiştir ve adamların tek isteği Trevor'ın gitmesidir. Trevor Reznik is a machinist in a factory. An extreme case of insomnia has led to him not sleeping in a year, and his body withering away to almost nothing. He has an obsessive compulsion to write himself reminder notes and keep track of his dwindling weight, both scribbled on yellow stickies in his apartment. The only person he lets into his life in an emotional sense is Stevie, a prostitute, although he has an infatuation with Maria, a single mother waitress working in an airport diner. His co-workers don't associate with and mistrust him because of not knowing what is going on in his life that has led to his emaciated physical appearance. A workplace incident further alienates him with his coworkers, and in conjunction with some unfamiliar pieces of paper he finds in his apartment, Trevor believes that someone or some people - probably one or some of his coworkers - are out to get him.
