Nobody knows where the fish went, and nobody knows why the fish went – but ever since they did, things just haven't been the same. In a committee room on Capitol Hill, three senators have a job to do: they must question a man on charges of trading rare marine commodities, and they must find out what he knows. Politics and the planet collide in a fiercely original play about the limits of science, the power of myths, and the things we can't control. Marek Horn's Yellowfin was premiered at Southwark Playhouse, London, in October 2021, directed by Ed Madden.
