1970s New York: determined to emerge from his powerful father's shadow and make a name for himself in Manhattan real estate, aspiring mogul Donald Trump (Sebastian Stan) is in the earliest days of his career when he encounters the man who will become one of the most important figures in his life: political fixer Roy M. Cohn (Jeremy Strong).

Seeing promise in young Donald, the influential attorney - who secured espionage convictions against Julius and Ethel Rosenberg and investigated suspected Communists alongside Senator Joseph McCarthy - teaches his new acolyte how to amass wealth and power through deception, intimidation, and media manipulation.

The rest is history.
