There are three children growing at Tammaru farm - one boy, Margus; and two orphan girls, Mari and Tiina. Tiina is lively and full of energy. Margus holds her very dear to him. Margus's parents want him to marry Mari instead as she is more their kind. Hotblooded Tiina is completely different from them and her mother was once executed for being a witch. Mari thinks that Tiina has bewitched Margus and cannot stand this, so she starts to publicly blame her stepsister for being a werewolf.
Unfortunately the movie Werewolf is not yet available on Paramount Plus.
