Crotchety Victorian businessman Ebenezer Scrooge (Alastair Sim) has no use for festivity, even at Christmas. After resentfully allowing timid clerk Bob Cratchit (Mervyn Johns) to have the holiday to spend with his loving wife (Hermione Baddeley) and family, Scrooge is swept into a nightmare. The ghost of his late partner, Jacob Marley (Michael Hordern), appears, warning that Ebenezer will be visited by three more spirits who will show the coldhearted man the error of his parsimonious behavior.
