[2] Anne is a lawyer working on three cases of rape and violent abuse of young women.

Peter's teenage son from his past marriage is Gustav, who lives in Sweden with his mother Rebecca.

The incident is reported to the police, but afterwards Anne finds an item in Gustav's laundry that was in her bag, stolen during the break-in.

From then on, Gustav joins in the social life of the family, for instance reading the Danish version of Alice's Adventures in Wonderland for the twin girls, which Anne herself also does.

A guest, Anne's sister Lina, witnesses the encounter and, upset, leaves the party.

Anne denies the accusation, claiming Gustav hates her for ending Peter and Rebecca's marriage.

Much later, Gustav visits the office of Anne and threatens to report her for the illegal relationship, but she replies he is not a credible witness and never will be believed.

He calls on her house at night asking for his father but is rejected by Anne who leaves him weeping on the ground.

In the end, Peter, Anne and the two young girls, dressed in black, drive in silence in their car, presumably to Gustav's funeral.

[5] The Los Angeles Times review referred to the "tricky brilliance" of the film.

The site's critical consensus reads, "Led by an exceptional performance from Trine Dyrholm, Queen of Hearts is a bold and uncompromising look at the darkness that can lie within family, directed with formidable skill by May El-Toukhy.
