Experimenting with a new potion, Dr. Henry Jeckyll finds himself turns into a very hairy brute. "I can grow a mustache in an hour and a half", he complains to his sarcastic man servant. "But I can never tell where it's going to come out." Then when a pretty French damsel in distress shows up on his doorstep, he really starts enjoying being able to "Hyde". Between ducking his tyrannical fiance, his domineering mother and the London police, he finds little time to get dates for his sister. This fast paced farce is full of fast lines, fast women and even faster exits.
