The filmmaker and protagonist of the film, Sunčica, is a vet on a journey across the Croatian coast and its islands where she neuters stray cats with a team of activists and another vet. She is convinced she is helping the animals until she is confronted with arguments of an animal right activist who claims that castrators like her, in addition to immediate mutilation, are doing long-term damage to cats and to the ecosystem in general. Sunčica begins to question the ethics of her work, especially as she faces a surgical procedure on her own body.
