Angela's husband and son died in hospital after a car accident. Since then the woman has been searching in vain for justice towards the doctor who carried out the fatal operation, Doctor Max. Desperation and obsession lead Angela in a paranoid state that dissociates her from reality. She follows the doctor day after day: behind the anonymous facade, the man hides a parallel life made of depravity and murders committed together with his colleagues Alan and Ivan. Discovering these new horrors, Angela turns to dark otherworldly forces to find the strength to eliminate the killers. This decision leads her into a spiral of violence and hallucinations, where pleasure and fear are confused and at the end of which there is a very high price to pay.
