Finnur (Kormakur), a prominent physician, is dealing simultaneously with both the death of his father and the increasingly erratic behaviour of his eldest daughter, Anna (Hera Hilmar). Perplexed, he suspects that Anna's new boyfriend, Ottar (Gisli Orn Gardarsson), may be the cause.

A frantic late-night call from Anna convinces Finnur that he must get the creepy Ottar out of his daughter's life for good. But Ottar's hold over her is unshakeable, the authorities prove completely useless, and he turns out to be much more ruthless than Finnur anticipated. Finnur feels increasingly powerless - a position that is both horrifying and heartbreaking.
