In the summer of 1939, on the eve of WW2, two young Cambridge ornithologists travel to a deserted Scottish island to study its bird life, not knowing that the site is being considered for anthrax testing. Cut off from the outside world with only the island’s leaseholder and his niece for company, their scientific project slowly transforms into an intense and thought-provoking psychological drama. David Greig is an acclaimed Scottish playwright.
