A 1946 black and white movie, It’s A Wonderful Life stars James Stewart.
He’s a businessman going through a difficult time, so much so that he goes to a bridge to throw himself into the raging river below.
Unknown to him, an angel has been sent to save him.
The angel – in human form – takes him on a journey round the town where he lives.
It’s a journey with a difference though because it’s as if he never existed.
He recognises everyone but they don’t know who he is.
