Nils Vik wakes up on November the 18th and knows it will be the day he dies. He follows his morning routine as voices from his past echo in his mind, and looks around the empty house one last time, before stepping onto his beloved boat. His dog, dead these many years, leaps aboard with him, and then the other dead begin to emerge --- from the woods along the fjord, from each of the ferry stops along the route, from his logbook full of memories and quotations and jotted-down notes about the weather conditions. The people from the past accompany him now, prodding him, showing him what he might have missed before, as he waits for his Marta, his late, remarkable wife, to finally join him on the boat again.

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. Nero, the baby Burmese python, soon becomes the apartment's fourth roommate. Thirteen years later, Mariam Lind goes on a shopping trip with 11-year-old Iben, who angers her mother by asking for a magazine one too many times. Mariam storms off, leaving Iben in the shop, and goes on a long calming drive. When she returns home, her husband is relieved to see her but terrified that Iben isn't also there. Detective Roe Olsvik realizes that there is much more to this case and these characters than their outer appearances would suggest.
