Tolkien meets George RR Martin in this hilarious improvised comedy soap opera in 25 episodes, running continuously and overnight across an entire weekend.

The annual marathon stars some of the funniest performers from the UK and overseas. With many going without sleep for 50 hours, this is theatre at its most exciting and unpredictable.

There will be live music throughout and an all-night bar. Drop in for one episode, a few, or join the party and stay for the whole thing!

Directed by Adam Meggido, Olivier Award winner with The Showstoppers and director of West End hit Peter Pan Goes Wrong.
