It is 1868, and a 22-year-old Bram Stoker has locked himself inside an abbey's tower to face off against a vile and ungodly beast, armed with mirrors and crucifixes and holy water and a gun, kept company by a bottle of plum brandy, praying to survive a single night, the longest of his life. Desperate to leave a record of what he has witnessed, Bram scribbles out the events that led him here.
