John Halder (Viggo Mortensen) is a German university professor who lives with his overly anxious wife, 2 children and a mother with senile dementia.
He writes a paper called, “The Case for Mercy Death on the Grounds of Humanity”, to explore his personal predicament and the justification of euthanasia.
Halder is set on a path that will lead to him divorcing his wife, marrying a young nazi sympathiser, Anne (Jodie Whittaker), and gaining an honorary SS commission.
Halder dons an SS uniform and visits a concentration camp where he is confronted by the reality that his choices and actions helped put into motion.
The site's consensus reads: "Though ambitious, Good stumbles in the transition from stage to screen, and Mortensen's performance isn't enough to cover its flaws".
