Synopsis of House of Frankenstein
House of Frankenstein is the first of the Universal Studios monster mashes. In short, mad scientist Niemann and “friend Daniel” his hunchback assistant escape prison and enact a series of revenges on the people who had him imprisoned. They murder a proprietor of a travelling show of horrors, impersonate him and revive his corpse of Dracula. Dracula succeeds in the first part of the revenge scheme, but Niemann abandons him to be destroyed in the sunlight. Niemann then travels to the ruins of Frankenstein’s castle. He hopes to recover the dead doctor’s secrets, but instead recovers both the Wolf Man and Frankenstein’s monster. He revives them both, but a romantic triangle unravels the plot.
