The first trailer for Amma Asante’s historical drama A United Kingdom is here, and Rosamund Pike and David Oyelowo are having a hard time reconciling their love with their countries’ animosity. Pike and Oyelowo play real life figures Ruth Williams and Seretse Kama, who fell in love during the time of apartheid in Botswana in the 1940s.

In the trailer, Williams (Pike) meets Kama (Oyelowo) at a party, and they try to have a relationship; a mixture of racism and politics thwarts their love at every single turn. Williams learns that Seretse Kama is actually a prince, and when he has to leave Britain to go back to Africa, he proposes to her. She marries him and returns with him to Botswana, where their relationship is tested by the native people who won’t accept her, and the British government who won’t accept him.

Amma Asante has ventured into studies of race and history before with her previous 2014 film Belle, also based on a true story, which was inspired by the 1779 portrait of Dido Belle, the illegitimate daughter of the Earl of Mansfield’s nephew. In the film, Belle lives with Mansfield in England as he rules on a case said to have contributed to the abolition of slavery in Britain.

A United Kingdom will have its world premiere at the 2016 Toronto International Film Festival.
