Plot

On a stormy night, a single mother discovers in shock the exact duplicates of all three of her pets and even her young son in their house. A little girl befriends what seems to be the ghost of a girl from the 1920s.

UFO Duplication - The young son of a farmer, Kyle, likes to go to the barn at night. One night in the barn, the family's dog is duplicated. His mother brings him back indoors to discover that his goldfish now has a twin, as does his hamster. Later, Kyle goes back to the barn, and his mother discovers two Kyles. Doyle, Donner, Cooper and team investigate and Kyle says the duplicates are from his ' alien friends', that they're gifts and that his 'alien friends' are scientists. Tests reveal that the boys are absolutely identical - one is a clone, but there is no way to know which one. However, one of the fish has died suddenly, and shortly thereafter, one of the hamsters died of a virus, so they test the boys T-cells, which fight viruses. One of the boys does not have any and is soon sick. Hendricks regresses Kyle's mother under hypnosis and she reveals that she has seen the aliens with her son. Cooper finds that one of the dogs is dying of tuberculosis. The sick boy has an operation to rectify his T-cell deficiency which saves his life and the two boys go home to their mother, with no clue as to which is the original and which is the duplicate.
