"National Theatre Live: Good" is a drama about John Halder, a liberal-minded German professor whose best friend, Maurice, is Jewish. As Germany faces its Second World War, Halder becomes seduced by the Nazi movement, rationalizing its atrocities to his conscience. The play explores how individual character flaws and moral detachment can lead people to endorse public monstrosity, tracing Halder's eight-year journey towards the upper echelons of the SS.
