Inseminoid

A team of 12 Xeno Project archaeologists and scientists begin excavations on a frozen planet. They uncover a cave system containing wall markings and crystals of unknown origin, suggesting a long-lost alien civilization. The discovery sets the stage for a deeper study of the ruins.

During one survey, a mysterious explosion cripples photographer Dean White and injures Ricky Williams. The incident disrupts the mission and raises concerns about safety and stability. The team scrambles to account for injuries and continuing risk.

Exolinguist Mitch theorizes that the civilization was built around dualism: the planet orbits a binary star and appears to have been ruled by twins. He interprets the wall markings as evidence supporting this idea. The theory reframes the team’s understanding of the ruins.

The crystals are found to be surrounded by an energy field, leading Sharon to speculate that the civilization was controlled by some form of chemical intelligence. This challenges the assumption of ruling physical leaders. The idea hints at non-human influence behind the ruins.

A crystal sample begins to pulsate, and the alien intelligence appears to take control of Ricky through a wound in his arm. He becomes delusional and heads back toward the caves, acting under the mind control. The boundary between science and danger grows thinner.

Outside the base, Ricky leaves the outer airlock door ajar and hurls Gail into twisted metal, damaging her environmental suit and trapping her foot. Her attempt to escape leads to a deadly struggle against the planet’s toxic atmosphere. The incident shows how quickly containment can fail.

Gail, trapped and unable to free herself, attempts a drastic measure with a chainsaw but ultimately succumbs to the planet’s toxic conditions. Her death underscores the lethal environment surrounding the mission. The loss weighs heavily on the remaining crew.

Kate Carson shoots the returning Ricky with a harpoon gun before he can reopen the inner airlock and evacuate all of the base’s air. The immediate threat inside is contained for the moment, but the danger from Ricky’s possession remains. The crew regroups amid escalating peril.

With the air crisis averted, Ricky and Gail are buried outside the base as casualties of the earlier chaos. Their deaths remove two team members and deepen the isolation of the survivors. The remaining crew faces an uncertain future in the ruinous base.

Mitch and Sandy return to the caves to collect more crystals, only to be attacked by a monstrous alien. Mitch is killed, and Sandy endures an assault that accelerates her pregnancy. The event heightens the peril and signals an emerging threat within the team.

The alien intelligence possesses Sandy, granting her strength to act violently. She kills Barbra and Dean and destroys Mitch’s remains, showing the depth of the threat and how it can manifest within the crew. The base’s security is overwhelmed by the possession.

Sandy uses explosives to blow up the base transmitter, plunging the base into communications chaos. Karl, Sharon, and Commander Holly McKay attempt to sedate her, but she reverts to violence. The facility’s ability to coordinate a response collapses.

Sandy’s rampage continues as she kills Karl and Holly. Mark, Kate, and Gary arm themselves with chainsaws to counter the threat. The survivors organize a plan to confront the possessed Sandy and protect the remaining crew.

Sandy harpoons Gary outside before returning to the base to give birth to hybrid twins. Mark overpowers Sandy and strangles her, ending the immediate threat. He and Sharon discover the newborn twins, signaling a dangerous new presence aboard the facility.

Twenty-eight days after contact is lost, a Xeno shuttle lands to inspect the missing team. The base lies in ruins, with occupants dead or missing. The twins have already stowed away in a shuttle storage compartment, leaving the threat to endure beyond the planet.
