The woman waits for her girlfriend to come back, which is whenever the aurora does. All summer, she wonders about the nature of her existence. Now, she waits in the cabin, the same one they rented together when her girlfriend was last alive. The girlfriend materializes and comes inside the cabin with her, and they head into the bedroom.

The woman thinks back to their first date, dinner plans in Los Angeles. They flirt over a sandwich, after which they go to the girlfriend’s apartment, and spend the night together. The Morning after, the girlfriend makes the woman breakfast. They talk about having a future together. The girlfriend shares her dream of building a house in Alaska to have together. Soon enough, the woman moves in to the girlfriend’s apartments, ever thinking about Alaska.

Now, in the cabin, the woman and the girlfriend talk about how they’ve missed each other. The girlfriend promises to visit more now that the aurora is here. When the sun arrives, however, she leaves.

The woman thinks back to their last argument. By surprise, the woman follows the girlfriend to the cabin in Alaska, despite her wishes to go by herself. After some arguing, the woman allows her girlfriend to do what she set out to do, which is to go into the river. By herself, in the cabin, the woman feels lonely. She heads outside and sees that her girlfriend is already long gone. She takes a photo of the river which took her.

After a day of sleeping in, the woman gets a knock on her door. It’s her girlfriend again. When her girlfriend calls the woman her girlfriend, they have an argument about commitment and clarity. The girlfriend thinks its ridiculous to put a label on themselves, as she’s now no longer living, instead coming and going with the aurora. She tries to comfort the woman, but she shies away. The girlfriend then disappears into the night.

The woman thinks back to how she flew back to Los Angeles after her girlfriend passed away. There, on the plane, she reminisces on the end-of-life party which she held and organized after getting diagnosed with a fatal disease. Back then, the girlfriend nonchalantly carries on with life, but the woman is left worrying about her and their future. She feels like she’s the only one who cares about the girlfriend’s soon death. They then start seeing a relationship therapist, where they talk about how the girlfriend is trying to make the most of her life before she dies, whereas the woman already feels stuck with grief and isolation from her. Eventually, they come to an understanding, and take a European trip together. After that, they plan the end-of-life party. Meanwhile, the woman has only been supportive as a facade, as she was planning, all along, to break up with her before the diagnosis came, because she no longer feels like they’re moving together through life. Now, she has stayed because she thought death would somehow bring them together. She has stayed in Alaska where, after her girlfriend’s death, she makes her out, somehow still alive, in the river. In this strange state, they apologize to each other and forgive each other after sharing the full truth.

The woman stays in Alaska for a few more days, waiting for her girlfriend to return, though she doesn’t yet show. She thinks she wants to apologize to her, though she doesn’t yet know if she can let her go. She asks, aloud, what she’s waiting for. Her girlfriend then appears, and they talk about letting go. The girlfriend feels okay keeping their relationship in transience, whereas the woman still wants there to be something between them. They come to an understanding again, and the woman musters the courage to let go. The woman says she needs to go away and do something, and only after eight months can they see each other again.

Across eight months, the woman secretly builds a cabin, using her girlfriend’s life insurance, in order to surprise her for when the auroras come back. She intends it to be a place where they can meet and be together, even if momentarily. Now, on its porch, she waits for her to come.
