Trevor Reznik, un empleado de una fábrica, padece desde hace tiempo un grave problema de insomnio, un mal que él esconde y que le provoca serias alucinaciones. Trevor no duerme desde hace un año.

Christian Bale made headlines with his jaw-dropping transformation for this film, shedding over 60 pounds to play an insomniac losing his grip on reality. But don’t let that overshadow the film itself: an acclaimed and nightmarish psychological thriller, reminiscent of Lynch, Fincher, and Aronofsky.
