Swedish couple Tobias and Elin dote on their only daughter, Maja. For her eighth birthday, they purchase her a
music box depicting three nursery rhyme characters from an antique store. However, during their vacation to
Skagen, Denmark for Maja's birthday, Elin is sent to the hospital due to an
allergic reaction to shellfish from her
mussel pizza at lunch. This is followed by the
sudden death of Maja in her sleep on her birthday (due to the mussels as she and Elin shared the pizza). Stricken with grief, Tobias and Elin's marriage begins to deteriorate as a result. It is unclear whether or not that they would intend to conceive another child. Three years later in
Sweden, Tobias and Elin go on a camping trip for vacation. They bicker constantly throughout the trip. As night falls, the couple is unable to find the campground they had intended to stay at and, despite Elin's protests, Tobias sets up camp in a wooded area off the side of the road. In the early morning, Elin leaves the tent to urinate and is accosted by three people and a dog who resemble the nursery rhyme characters from Maja's music box: the jovial and sharply dressed leader Mog, the hulking and animalistic Sampo - who carries a dead white dog at all times, and the stoic, witchlike Cherry - who owns a vicious brown
Staffordshire Bull Terrier. They torment Elin while Tobias watches from the tent, unsure of what to do, and eventually both are murdered. Tobias and Elin inexplicably awaken again, with Elin having no memory of the previous events and Tobias chalking it up to being just a dream. When Elin leaves the tent, the two again encounter the strange trio and are again murdered. As the cycle repeats, Tobias begins to understand that they are trapped in a
time loop and attempts various means of escape with each new cycle, only to be killed and awaken each time. Eventually, a loop starts in which Elin awakens with Tobias gone and encounters their wrecked car with Tobias nowhere to be found. Elin follows an enigmatic white cat and enters a building in which the three characters perform a
shadow play for her; two parent rabbits have a child who dies, and the parent rabbits are subsequently driven apart by their grief. As another loop starts, Tobias awakens in a panic and drags Elin to the car for another attempt at escape. They hit and kill a dog resembling the dead dog belonging to the trio and crash their car in a ditch. In their despair, Tobias and Elin comfort one another. Their fate is left ambiguous, but it is implied that through their love and acceptance of their mutual grief, they have escaped the time loop. ==Cast==
