Market trader Pete Johnson deals in stolen goods, gives his young son Mike an early Christmas present, an electric racing game, but it's faulty and blows up, hospitalising the boy. Pete initially lies to hospital staff over the cause of his son's injuries but eventually produces a replacement, which indicates the game is manufactured by the Wings' toy company. However, Mr Wing informs Eddie that it was withdrawn because of the fault and stored in the warehouse. On examination, it's found that ten copies have been stolen. Eddie must track them down to ensure a merry Christmas.
