Abi Morgan's new play is based on a book that is in turn based on the recorded conversations of a couple who shared a somewhat unusual relationship arrangement for 30 years.
He and She (Danny Webb and Saskia Reeves) meet as students and then again in their earlier 40s which is where the play begins. Both have failed marriages behind them and start an affair which leads to an assessment of what they each get out of the relationship.
She convinces He to start an experiment with a contract. He provides her with a home and an income while She provides him with 'mistress services', essentially sex anyway he wanted it. She is a teacher and feminist and He a successful businessman.
