After being the sole unfortunate witness to a domestic quarrel that ends up in a murder, Sandu finds himself at odds with two very close neighbours. One is the bizarre murderer, the other is his very own conscience.

In this brilliantly executed slow-burn thriller from Romanian director Radu Muntean, a family man who witnessed the prelude to a murder determines to keep his mouth shut and mind his own business — until the possible killer turns up at his door one day and begins to ingratiate himself into the lives of his wife and son.
