Doctor Who

BBC1, 6.55pm, Sun

In 1955, in Montgomery, Alabama, an African-american woman refused to give up her seat to a white passenger on a racially segregated bus.

Her name was Rosa Parks, and she became a heroine of the civil rights movement.

Many have wondered what they’d say to her, if they had the chance to go back in time. And that’s the idea behind this instalment as the Doctor takes her companions back to to that dangerous world.
