Hetty Wainthropp Assassinates
An elderly lady is sent back In time to a Charlie Chaplin premiere in 1928 to assassinate Adolf Hitler. Unfortunately Vodafone cut her off just as she's receiving her instructions, with the result that she believes that she has to kill a small dark-haired German man with a moustache. She goes on to kill Albert Einstein, the atomic bomb is never invented, the Nazis win the war, and, erm, we all end up dead. The show is perhaps lacking a little in the "feel-good" factor.
