In this episode, romance is in the air at Cliveden. Boutique hotel brand Mr and Mrs Smith capitalise on the hotel's reputation for scandal by shooting a commercial in an intimate bedroom. There's also romance on the river. And Lydia plans the most lavish wedding of the year, for a Japanese supermodel and her British fiancé. No expense has been spared, with a 10-tier cake, bespoke Valentino dress, and half a million pounds worth of jewellery. But the spectacular firework display is in jeopardy as Dom struggles to serve dinner before the curfew.
