This episode sees Myatt take his students on to a rooftop overlooking London's Southbank, where they get to grips with painting in the style of one of modern art's great revolutionaries, George Braque. It's a tough day for John. His first task is to take the fear out of painting a cubist landscape and give the three students the confidence to think and paint outside the box. He teaches them how to paint using cubist language, but the students are completely daunted. Amateur artist Edna Eckett is thrown by the limited palette and feels lost without any primary colours. Actor Rick Warden is a big bag of nerves and Cassie McDaniel is a portrait artist who steers clear of landscapes. With John's guidance, can these three translate an urban landscape into a cubist masterpiece that even Braque would be proud of? And back in the studio, John shows goes over one of his cubist paintings, a Picasso. Would you be able to tell it's a fake?
