Time Flies.

The short starts with a duel in the Old South wherein a man inadvertently saves one of the duelist's lives for which he is given a watch. Years pass and we next see the grandson, impoverished and heading to the big city for work (taking the watch with him). His ma gives him a pigeon in case he wants to send a message back home. The watch is the key to getting a fortune and a vamp and her cohort want it.
