A plane crash, office politics and the fate of mankind are just three of the themes that litter Tom Basden’s Holes, a new comedy that maroons a bunch of misfits on a deserted island. But, while it begins as a comedy, it soon gives way to something much more sinister.

Created by the team behind 2009’s Fringe First winning Party, Holes throws together colleagues Gus (Mathew Baynton), Ian (Daniel Rigby), Marie (Katy Wix) and teenager Erin (Bebe Cave) as four very different survivors of a mysterious plane crash. But as they wait for rescue, a series of unfortunate events threaten their view of the world, and eventually, each other.

While Holes initially showcases Basden’s funny dialogue and Philip Breen’s direction, it slowly evolves and changes from comedy to tragedy, and then onto something much more disturbing. The problem with the play is that it seems to suffer from an identity crisis: is it a comedy? Is it a drama? There are many unanswered questions in Holes, which leads a promising piece of new writing to come to an unsatisfying and sudden conclusion.
