A man turns up at Lucy's door claiming to be the brother she hasn't seen in 10 years. But why has he come? Is it really him? And what happens when there's another knock at the door? Forced to confront the messy inner workings of sibling love with its petty resentments, casual cruelty, profound betrayals and implicit understanding, can the bond between brother and sister be rebuilt? The Human Ear premiered at the Edinburgh Festival Fringe 2015, in a production by Paines Plough.
