Maxwell Kane is Kenny Kane's son who has lived with his mother's parents for the last ten years. Kenny Kane, also known as Killer Kane, has been in jail for all of that time. Once he makes parole, Grim and Gram, Maxwell's grandparents and legal guardians, place a restraining order on Mr. Kane to deter him from getting close to their home or Maxwell. Since Killer Kane went to jail, he never had contact with Maxwell because Grim and Gram thought it best that the boy not have any contact with his murderous father. When Maxwell does meet his father, Kane tells his son that he sent letters from jail in an effort to keep in touch. Maxwell never received any of the letters, which Kane supposed; but once out of jail, he wanted to get his son back. Because of the restraining order, though, Kane couldn't just walk up to the house and ask to see his son; so, he makes his way into the house in the middle of the night on Christmas Eve and kidnaps Maxwell.
