What Is Solaris About?
The premise of Solaris in 300 words, with nothing given away. The full story follows below.
In the cold silence of deep space, a solitary research station circles Solaris, a planet whose entire surface is a roiling, alien ocean. The ocean is more than a body of water; it is hinted to be a vast, thinking entity that reflects the inner lives of those who study it. The station’s crew lives under a perpetual hum of instrumentation and a lingering unease, as subtle phenomena begin to blur the line between reality and imagination.
Kris Kelvin arrives as a psychologist tasked with deciding the station’s fate. He carries the weight of a final conversation with his aging father and the lingering echo of a past love, both of which color his perception of the mission. The crew he meets—Dr. Snaut, a pragmatic thinker; Dr. Sartorius, whose curiosity pushes the limits of scientific inquiry; and the late Dr. Gibarian, whose absence still haunts the corridors—are each grappling with the planet’s enigmatic influence in their own way.
The film’s tone is contemplative and almost meditative, bathing the sterile corridors and the endless star‑filled void in a soft, dream‑like quality. Light and shadow play across the characters’ faces as they confront questions of memory, guilt, and what it means to be human when confronted by something that can manifest thought itself. The atmosphere is thick with intellectual tension, inviting the viewer to ponder whether the true mystery lies in the alien ocean or within the minds of those who stare at it.
As Kris Kelvin settles into his role, the station becomes a crucible for introspection. The subtle disturbances that ripple through daily routines hint at deeper undercurrents, suggesting that Solaris may be a mirror for the crew’s hidden obsessions. The story beckons with a quiet promise that the answers—if they exist—are as elusive and profound as the planet itself.

Spoilers ahead
Kris Kelvin, Donatas Banionis, a psychologist, is poised for an interstellar mission to Solaris to decide whether the decades‑old research station circling a vast ocean world should continue. He spends his last day on Earth with his elderly father and a retired pilot named Burton. Years earlier, Burton had joined an exploratory team at Solaris but was recalled after reporting unsettling sightings, including a four‑meter‑tall child on the planet’s surface of the water. A panel of scientists and military personnel dismissed these visions as hallucinations, yet the remaining crew members now report similarly strange phenomena. Before departure, Burton confides that he recognizes the child’s face as someone who was orphaned when a Solaris explorer vanished.
Upon arrival at the Solaris station, Kelvin finds the outpost in disarray. Dr. Gibarian, Sos Sargsyan, has killed himself, and the two surviving crew members—Dr. Snaut Jüri Järvet and Dr. Sartorius Anatoliy Solonitsyn—are increasingly unstable. Kelvin also glimpses figures who were not part of the original crew. Gibarian has left a cryptic farewell video urging Kelvin to trust what he is experiencing, showing two appearances of a little girl and insisting he is not insane; if strange things occur, it will not be Kelvin’s fault.
That night, Hari Natalya Bondarchuk, Kelvin’s wife who died ten years earlier, materializes in his sleeping quarters. He is terrified, and in a moment of desperation he launches a replica of his wife into space. Snaut explains that the visitors, or “guests,” began appearing after the scientists conducted radiation experiments aimed at the swirling surface of Solaris, in a desperate bid to understand its nature.
Later, Hari returns again, this time with a steadier presence. Kelvin accepts her and they fall asleep together, but when he briefly leaves, she panics and injures herself trying to escape. Before long, Snaut and Sartorius tell Kelvin that Hari is not the real person but a being crafted from his memories of his wife. She thinks and feels as if she were human, yet she is not, and Sartorius suggests that the visitors might be fragile but dangerous beings that could be destroyed with a device called “the annihilator.” In a later discussion, Snaut even proposes beaming Kelvin’s brainwave patterns at Solaris to help it understand him and halt the disturbances.
As Hari grows more autonomous, she learns the truth about the original Hari’s suicide ten years earlier. The scientists gather to confront the mystery in a birthday‑party setting that devolves into a philosophical debate, with Sartorius reminding Hari that she is a memory, not a person who truly exists. Overwhelmed, Hari drinks liquid oxygen and dies again, only to experience a painful, immediate resurrection. On the planet’s surface, the ocean swirls faster, forming a funnel that hints at a looming encounter with Solaris itself.
Kelvin falls ill and dreams of his mother, a young woman who tends to his arm. When he wakes, Hari is gone; Snaut reads Hari’s farewell note, in which she explains she asked for destruction. Snaut adds that broadcasting Kelvin’s brainwaves into Solaris has caused the visitors to stop appearing, and islands begin to form on the planet’s surface. Kelvin contemplates whether to return to Earth or stay with the crew.
In the film’s surreal final act, Kelvin appears to be at a family home from the past, where he embraces his father. The image slowly shifts, revealing that the setting is in fact one of Solaris’s islands, leaving the truth open to interpretation and inviting contemplation about memory, guilt, and the nature of humanity. The island‑bound ending lingers, suggesting that consciousness and longing can shape reality just as surely as science does.

Where and When Is Solaris Set?
Solaris is set in Solaris space station and Solaris planet. Here is why the place matters to the story.
Where
Solaris space station, Solaris planet
The setting centers on a remote research station orbiting the oceanic planet Solaris. The station becomes a site of unexplained phenomena as the crew experiences visits from beings created by Solaris' mind. The planet and its guests shape the crew's investigations and the choices they face.
- 🌌 Space Station
- 🌊 Ocean Planet
- 🔬 Scientific Outpost
What Are the Themes of Solaris?
3 ideas the story keeps returning to, among them Memory, Grief and Reality.
-
01
Memory
Memory drives much of what happens on Solaris. Hari is born from Kris Kelvin's memories of his dead wife, challenging the boundary between person and reconstruction. The crew debates whether the visitors are real or projections, forcing a test of scientific objectivity against intimate recollection. The film uses memory to probe identity, guilt, and longing.
-
02
Grief
Kelvin's grief over Hari's death compels him to engage with the replica, shaping his emotional responses and choices. Hari's presence intensifies questions about longing, responsibility, and the costs of reconnecting with what is lost. The scientists' cool rationality contrasts with the chaotic force of unresolved sorrow. Grief becomes a driving force that reshapes relationships aboard the station.
-
03
Reality
The line between reality and illusion blurs as the guests mimic human behavior and memories. Scientific attempts to understand Solaris—like the annihilator or broadcasting brainwaves—struggle against the planet's mind-made phenomena. The narrative uses this tension to examine what is truly real when memory and desire conjure convincing counterparts. The ending leaves the nature of existence open to interpretation within this isolated world.
