Sophie and Clive are inspired by the work of Marie Curie. Clive creates a play about Marie's life, which Sophie thinks is excellent and then decides to put on a production of it. Sophie refuses Clive's offer of playing Marie Curie. Then Emma decides to get in on the act. She makes Clive agree with everything she says, using Adil's help, and turns the play into an all singing, all dancing West End spectacular.
