The Boy from Before (2009)

The story of odd-one-out Sam. Already expelled from three schools for disruptive behavior, he starts afresh feeling shy, apprehensive and out on-a-limb. He's never wanted to cause a commotion at any of his schools, it's just he seems to have a strange effect on electrical equipment, particularly when he's feeling upset or anxious. He finds a friend in fellow misfit Jack, the thing is nobody else can see Jack and Sam ends up on the receiving end of the school bullies' taunts. Jack takes Sam back-in-time and introduces him to his world but in his own world the bullies take things too far. Injured and laid up at home, Sam realizes he does have other friends at school. He finds a way of telling them about Jack, a ghost from the past, and together, they go to Jack's world.
