Liv has a lot of secrets. For her, home is the picturesque town of Ålesund, perched on a fjord in western Norway. One night, in the early-morning embers of a great party in the basement apartment she shares with two friends, Liv is watching TV, high on weed, and sees a python on an Australian nature show. She becomes obsessed with the idea of buying a snake as a pet. Soon Nero, the baby Burmese python, becomes the apartment's fourth roommate. As Liv bonds with Nero, she feels extremely protective, like a caring mother, and she is struck by a desire that surprises her with its intensity. Finally she is safe.

Thirteen years later, in the nearby town of Kristiansund, Mariam Lind goes on a shopping trip with her 11-year-old daughter, Iben, who angers her mother by asking for a magazine one too many times. Mariam storms off, leaving her daughter in the shop, expecting that she’ll find her own way home. When she returns home later that evening, Iben isn't there. Detective Roe Olsvik is assigned to the case of Iben's disappearance; he has just turned 60 and is new to the Kristiansund police department. As he interrogates Mariam, he instantly suspects her - but there is much more to this case and these characters than their outer appearances would suggest.
