The X-Files: Season 5 Episode 6

Christmas Carol (1)

On her Christmas vacation with her brother’s family, Scully receives a mysterious phone call from a familiar voice who says, “She needs your help. Go to her.” The phone call leads Scully to a murder case where the victim’s 3-year-old adopted daughter bears an uncanny likeness to her sister, Melissa, at that age. The emotional roller coaster that follows has Scully believing that her sister had a baby during a period when she traveled the country and she tries to adopt the child, knowing that caring for the little girl would change her life.
