Torchwood encounter an alien, Adam, who can manipulate the memories of any person he touches. He implants false memories into the team, making them believe they have known him for three years. As a side effect Gwen loses all memory of her fiancé Rhys and treats him like a stalker. Adam also reveals, alters, and completely fabricates other memories. Jack is haunted by memories of his brother, Grey; Toshiko becomes more confident due to her "love" for Adam; and Owen becomes a geek with an unrequited crush on Toshiko. After Ianto discovers Adam's secret, Adam implants a belief in Ianto, accompanied by terrible memories, that he is a serial killer. Jack recognises the threat and realises that the solution is to give the team short-term amnesia pills to erase their memories of the past forty-eight hours. However he is also faced with the knowledge that if he takes the pill he will lose all memories of his father. Toshiko takes the pill knowing that she will go back to being the person who had no flat warming because she had no friends to invite, and is reluctant to let Adam go.
