Rosa has arrived in London from Poland to look for her younger brother, Mikhail. He is supposed to be staying with their English father, but when she visits the house she finds it's locked up and there's no sign of either of them. Stef is running away from her boyfriend Oliver. Frightened, friendless and far from her family, she needs somewhere to hide. All three find refuge at 11 Bellevue Gardens. Here, its owner Leonie once herself found sanctuary, now opening her house to others in need.
