Dilemma (1962)

The story begins when Toby (Ivan Jackson), a young English businessman, arrives in South Africa to take charge of a publishing firm. He knows little about apartheid and so at first sees no contradiction in developing a relationship with an elite, upper-class white woman and with a woman dedicated to fighting apartheid. But as Toby makes friends with one of the black South Africans (Zaku Mokae), and as he registers both the subtle and more obvious, deep-seated racial prejudices of the minority white population, some of the truth of the oppression here begins to dawn. That is brought to a head when tragedy strikes.

Unfortunately the movie Dilemma is not yet available on HBO Max.
