Louise discovers that the heptapods' written language is non-linear. They write a sentence all at once—the beginning, middle, and end are a single circle. There is no "before" or "after" in their text.

At the absolute center of Arrival is its rigorous intellectual treatment of linguistics. The film introduces two distinct extraterrestrial entities, nicknamed "Abbott" and "Costello," who belong to a species called Heptapods due to their seven-limbed physiology. The Orthography of Heptapod B

The question the film asks is devastating:

In the climactic third act, Louise realizes the truth: These aren't memories. The daughter hasn't died. She hasn't even been born yet. In fact, she hasn't even met the father yet (spoiler: it’s Ian).

The film argues that the value of life is not measured by its length, but by its depth. The pain of losing Hannah is so great that it almost destroys Louise—but the experience of Hannah is worth that pain.

The movie begins with Dr. Louise Banks (Amy Adams), a renowned linguist who is recruited by the US military to communicate with aliens who have landed on Earth. The extraterrestrial beings, referred to as "heptapods," have arrived in 12 different locations around the world, and Louise is tasked with deciphering their language and understanding their intentions.

Louise looks at Ian (who does not yet know their future) and makes a conscious decision. She chooses to love him. She chooses to have Hannah. She chooses to hold her daughter, read her stories, and watch her laugh, knowing with absolute certainty that she will have to watch her die.

Because Louise has fully absorbed the Heptapod language, her perception of time has become non-linear. She sees her entire life at once: her teaching career, meeting Ian, the birth of their daughter Hannah, the diagnosis of a rare incurable disease, Hannah's death as a teenager, and Ian leaving her because he couldn't bear the pain.

As Louise's understanding of the language deepens, she begins to experience more vivid and disturbing visions of her past and future. Her growing connection with the heptapods leads her to realize that their language is not just a means of communication but a way of perceiving reality.

The film shuns glossy, futuristic imagery. Instead, Young utilizes natural, soft lighting, muted color palettes, and shallow depth of field, giving the movie an intimate, documentary-like texture.
