Written by David Gillespie and Colin Wakefield, Sleep No More is a supernatural thriller set in a theatre, abandoned for the last sixty years following the accidental death of a child during rehearsals for Murder by Poison, a Victorian thriller. Now the great-grandson of the theatre’s original owner has set about restoring the theatre to the glory of its former heyday, and to cap his plans he’s intent on reviving the very same play to re-open the renovated theatre. Despite warnings not to proceed with the show, rehearsals progress, and unusual and mysterious occurrences begin to mount with deadly and terrifying consequences.
