Whitechapel, 1888. No time to be a woman alone after dark. Psychopath on the loose; could be a surgeon, member of the Royal Family or mysterious man you're falling in love with. Nothing is certain. What's left for a working girl to do but take to the streets and make a song and dance about it? Musical thriller based on true events that occurred in that fateful year. Contemporary take on a story that has horrified and fascinated generations. ***** (Guardian, for Jolly Folly of Polly the Scottish Trolley Dolly).
