New BBC audio drama Purple Heart Warriors is about some of the Second World War's least talked about soldiers, the Japanese Americans of the 442nd. We all know Hannah is fascinated by war stories, but not everyone is, so she's asking director Jessica Dromgoole about how you make a story like this accessible to everyone, and what it tells us about war, loyalty, immigration and much more.

* Purple Heart Warriors starts on the BBC World Service on December 11 and the whole series will be available to listen to on BBC Sounds from December 9.
