The Kinship is an alien species that can take over any living person and control its actions. Another species had sought to take over The Kinship's world, during an event known as "The Great Destruction". To survive, The Kinship abandoned their own world, hoping to live on another life-supporting planet. They used an egg inside a meteor to transport themselves across the galaxy, hoping the meteor would crash on another inhabited planet.
In 1980, The Kinship's meteor crashed in the center of Chester's Mill. Teenagers Melanie, Pauline, Sam and Lyle found the meteor in the middle of the woods. As they approached it, four hand prints glowed, one on each side of the meteor. Each of them placed his or her hand on the meteor, which triggered it to open, revealing a glowing pink egg. Attracted by the egg, Melanie picked it up. However, Lyle pushed her into the meteor, and she died.
Had she stayed alive longer, Melanie would have been infected by The Kinship, and a dome (a device that traps and protects life forms inside it) would have lowered over the town, while a mini-dome descended over the egg (an energy source), and Melanie and her friends, as the first life forms to have come into contact with the egg, would have been pulled underground, into a large cave which forms instantly. There, they would have been able to view the town from within a large "Queen-size" cocoon. But since she died, it didn't happen then. Panicking, Melanie's friends buried her and the alien egg, swearing never to talk about the incident again.
Seriens händelser sparkades av när ett annat intakt ägg hittades och aktiverades, denna gång utan att någon av aktivatorerna omedelbart dödades.
Now, in 2013, two archaeologists, Christine and Eva, search for an intact egg, which they believe to be located in Chester's Mill. They work for a large energy company called "Aktaion," which, in the past, studied other eggs that crashed to earth. The other eggs had broken when they'd crashed, so, when the eggs were touched, domes did not come down.
Christine and Eva find the intact egg. As Christine holds it, the infection process begins, and The Kinship beings transfer into her, as she screams in pain. Once the process is complete, a large pink explosion occurs, and the dome lowers around them, a mini-dome descending over the egg. Christine and Eva get sucked into a large cave, which appears below them, and get cocooned.
