Mia is anxious about going to her father’s birthday/engagement party for numerous reasons: her relationship with him is strained due to her parents’ divorce, she will be meeting her future stepmother and stepsister for the first time, and she also has to share the news that she’s engaged to her live-in boyfriend. Once in the presence of her father, and in observing how different he is with his fiancée, Elisabeth (played by The Girl with the Dragon Tattoo’s Lena Endre), Mia finds herself more closed off than ever and resentful like a petulant child…especially when her father leaves her stranded on an island with her new “family.”

Stuck and wanting to be polite, Mia is forced to spend time with Frida, Elisabeth’s daughter. Light and easygoing, Frida can’t help but tease cold and uptight Mia to get her out of her shell. This very quickly ends up also getting Mia out of her clothes after a chemistry-filled moment in the forest and a magical midnight swim. As the two women begin a heavy and passionate love affair (which moves incredibly fast, even by lesbian standards), they must both figure out how this surprising turn of events will fit into their current lives and their new family dynamic. Do they bravely take a chance on love at the risk of turning the lives of everyone around them upside down? Or are long buried secrets easier to ignore?
