As a result of the catastrophe over the Atlantic, the plane , which,
among other passengers, is Dr. Martin Evans, falls into the ocean.
Aliens from the planet Orange rescue the surviving passengers by
removing them from their memorydetails of the disaster. The rescued
unsuccessfully try to figure out what happened to them. Being in a
dilapidated plane, which is in an unknown space, the absence of debris
and victims of the disaster cause confusion and ambiguous assessments
in them. There is an obsessive feeling that someone is watching them.
Trying to get in touch with these unknowns, passengers receive a
signal that they are being heard. They are then greeted remotely,
announcing their salvation. For "official negotiations," the aliens
invite Dr. Evens as the most educated of the passengers. From them,
the doctor receives information about the planet from which they flew,
as well as the purpose of their visit. As it turned out, their planet
is smaller than Earth, but more ancient.At some point, its inhabitants
became unbearably lonely in the depths of space and they sent an
expedition in search of other civilizations. Aliens also introduce
Evens to their exceptional ability totelepathy , teleportation and
longevity . They are benevolent, but emotionally more restrained and
more strict in their reasoning than earthlings.
Further events develop on one of the islands in the northwestern part
of the Atlantic Ocean, where the aliens deliver passengers. In long
dialogues with aliens, the doctor tries to convince them to open up to
the world and help him in his scientific work dedicated to the
extension of human life.
An alien reconnaissance ship is attacked by an earthly warplane,
resulting in the death of the alien Buami. In connection with this
incident, as well as after the aliens got acquainted with the sad
earthly realities, such as hunger , wars , diseases , the disunity of
peoples and states, the absence of uniform laws, the aliens inform
Ivens of their decision: contact with earthlings and the opportunity
to reveal to them the secret of prolonging life premature. Aliens
disappointed chtóthey learned about their long-awaited "brothers in
mind". As a result, they refuse Evans further cooperation, citing the
fact that people have not yet reached true morality, and they erase
from all the saved, except for Ivens, the memory of what happened. In
turn, the doctor promises the aliens to be silent about what he
learned from them, assuring that earthlings can even go to death for
the sake of an idea.
Orante, a woman from the alien crew, despite the moods of the other
crew members, feeling the sincerity of the doctor's motives, feels
sympathy for him and realizes that not all earthlings are the same. In
the process of communicating with Dr. Orante, he decides (contrary to
the instructions of his fellow tribesmen) to share earthly life with
people, whatever the cost.
The aliens leave the passengers on the island, where the search and
rescue teams find them. Many media outlets report the miraculous
rescue of those who survived the disaster, and the public is showing
interest in them. Dr. Evans returns to daily life, but his memory
retains the details of an incredible meeting. He reconsiders a lot and
understands that the results of his scientific works can be used by
those who pursue purely selfish goals (which the aliens feared). For
this reason, Evans, speaking at the conference, announces that he is
not going to continue research on finding ways to prolong human life.
The position of the doctor does not find understanding among the
scientific community, and his wife believes that he simply fell into
The alien mission is still on the planet, but is already preparing to
leave it. Orante periodically visits Ivens at his home, becoming
invisible when necessary. However, the doctor's wife sees more and
more oddities in her husband's behavior.
The doctor is already being followed by special services. Once agents
break into his house when Orante is also there. She manages to
disappear, and the agents search and interrogate Ivens. Intelligence
agencies need information about what really happened in the North
Atlantic, as the military began to notice strange phenomena in the
area of the plane crash.
At a certain moment, having received a sign from Oranta that the time
has come to reveal the secret, the doctor informs the agents about the
aliens: who they are and for what purpose they arrived on the planet.
The agents are trying to take the doctor into custody. Orante helps
him escape, stopping the kidnappers with hypnosis. For a while, Evans
and Orante leave their pursuers.
The doctor, in spite of everything, is going to tell people the truth
about guests from a distant world. But what was conceived is not given
to come true: they are pursued, Oranta teleports, and Ivens, being
ambushed on the road, suffers an accident and dies. Orante appears.
She's trying to help the doctor. She is surrounded, she first resists
with the help of her unusual hypnotic abilities, but then she herself
dies from a gunshot wound...
