Mary Shelley (Richardson), Lord Byron (Byrne), Percy Bysshe Shelley (Sands), Claire Clairmont (Cyr), and Dr. John Polidori (Spall) spend the night of June 16, 1816 in a Swiss villa telling each other ghost stories and experimenting with laudanum and sexual partner combinations. The dreams and realizations of the night will color their lives ever after. Interesting premise, well-carried out, although burdened by director Russell's typical excesses.
