Una Stubbs and Richard Bacon present from the prestigious Tate Britain gallery on the banks of the Thames in London, where the amateur artists face three challenges capturing the human form.

Two semi-naked men greet the remaining artists, which leaves several hot under the collar as they struggle with the first challenge set by expert judges Lachlan Goudie and Daphne Todd OBE - to capture the anatomically correct body shape, proportions and flesh tones of two loincloth-draped Greek god life models.

In a difficult quick-draw challenge, the amateur artists must use coloured pencils for the seemingly impossible task of capturing a rhythmic gymnast and her flickering ribbon. Lachlan gives his expert tips on how to suggest motion when sketching.

Also, the artists take on their final challenge of the week - which proves emotional for some - painting a powerful and passionate flamenco dance in coloured chalk and pastel. And we learn which artist's painting is summed up with the phrase 'I did earlier snort with laughter looking at it'.
