David tells Adam that he is having problems with his sex life, so Adam seeks advice for "a friend" from Pete. Pete assumes Adam's "friend" is actually Adam himself and tells Jenny that Rachel cannot satisfy Adam in bed. Rachel decides she and Adam need to spice up their relationship by disclosing their fantasies to each other—and hers is to have sex in a shop window. He gets the keys to a charity shop from a friend and they sneak in after closing time. The fantasy quickly turns into a nightmare when a ramraider drives a car through the shop window. The police arrive and Adam and Rachel are taken to the police station. Meanwhile, David decides to bypass traditional sex therapy by visiting a prostitute under an assumed name. Pete and Jenny start having sex for the first time since the birth of their baby, acting out her fantasy of a squire and his lowly servant, though his imagination is repeatedly invaded by an attractive barmaid.
