Nina and Paul's marriage is over. They are just waiting for an opportunity to teach their son Tim. During a chance encounter, Nina flirts with Viktor, her son's hockey coach, and goes home alone with him. A decision with serious consequences. Nina is almost raped by him, defends herself and kills Viktor in the process. Paul has followed the two and witnesses the accident, which makes a self-defense situation implausible. Agitated, the two drive home without notifying the police.
