[2][3] Living in Paris, 24-year-old David is close to his sister Sandrine – a single mother – and her seven-year-old daughter, Amanda.

Sandrine goes to the park with friends where, in a terrorist attack, she is killed and Lena injured.

David looks after Amanda but, even with the help of his aunt Maud, he isn’t sure he can cope and considers sending her to a children’s home.

Amanda initially wants to stay with Maud but, as she and David begin to bond, she changes her mind.

He then takes Amanda to London to meet his estranged mother Alison, and to visit the Wimbledon Tennis Championships.
