Authors Lord Byron, Mary Shelley (née Godwin) and Percy Shelley get together for some philosophical discussions, but the situation soon deteriorates into mind games, drugs, and sex. It is a fictionalization of the summer that Lord Byron and the Shelleys, together with Lord Byron's ex-lover Claire Clairmont and his Doctor John Polidori, spent in the isolated Villa Diodati by Lake Geneva. It is there they devise a contest to adduce the best horror story to kill the dullness of summer. It is also there that one of the world's most famous books was given life—Mary Shelley's Frankenstein.

He has survived everything: electoral battles, terrorist massacres, loss of friends, slanderous accusations; but now certain repentant mobsters implicate him in the crimes of Cosa Nostra.
