On the picturesque island of Sunnanö in Sweden’s archipelago, Anna-Lisa and her son Oskar manage a well-loved bed and breakfast. Anna-Lisa has called her daughter Jonna, an actress, and her son Lasse, who is known for his opportunistic nature, back to the island. This marks the first time in years that the siblings have been together. When Anna-Lisa is discovered dead one morning, they find out she had been suffering from terminal cancer. Her will reveals that the siblings must jointly operate the family B&B for a year to inherit it. This is her final attempt to bring her children closer. However, this arrangement will also force them to face unresolved family issues, current emotional entanglements, and a deeply buried, sinister secret in a most regrettable location.
