When a girl's body is found on a beach in Poland's Tricity, a prosecutor teams up with the victim's mother on an impassioned quest for the truth.

When their father leaves on a business trip, Antek and his older sister, Paula, are left alone for the weekend in their sleek, high-tech smart home. Antek blames Paula for their mother leaving them - and their strained relationship goes from bad to worse when Paula invites her friends over for a party. The night takes a dark turn after the unexpected and unpleasant visit of a schoolmate. What was meant to be a carefree weekend quickly descends into terror, as the supposedly secure house becomes a deadly trap.
