Anu regularly consults with Heloisa in her practice, and she notices a pattern: whenever Heloisa falls in love, she begins to suffer from intense, tormenting obsessions directed at her beloved. Heloisa’s complex and disturbed psyche captivates Anu, both on a professional level and a personal one, though she struggles to fully understand why. Suddenly, Heloisa abruptly discontinues therapy, leaving Anu puzzled and unsettled. The situation takes a surprising turn during a midsummer gathering with friends, when Anu’s son, Antti, arrives accompanied by his new girlfriend—who, to Anu’s shock, is Heloisa. This unexpected encounter forces Anu to confront her own boundaries and dredge up painful memories of her therapeutic relationship with Heloisa. As these memories surface, they reveal a dangerously obsessive bond that threatens to unravel everything Anu holds dear.
