John Kane sits on a hospital trolley. Very shortly, a giant lobster, two women called Mary, a very old man and a jazz percussionist arrive. Then everything starts. Enda Walsh's Medicine is a dark and frequently absurdist play. Devastatingly funny and profoundly moving, it examines how, for decades, we have treated those we call 'mentally ill'. This edition also includes Walsh's play The Same , about two women who meet in a psychiatric institution.
