The grand final sees presenters Una Stubbs and Richard Bacon travel to Devon's picturesque south coast as the final four amateur artists battle it out to be crowned the winner. With just three challenges left to impress the judges, Lachlan Goudie and Daphne Todd OBE, the amateur artists get to grips with their first challenge - capturing a sense of Britain's seafaring heritage at Dartmouth's Royal Naval College. With the prize in sight, one artist goes all out to impress the judges, risking everything. The finalists have already sketched the human body in motion - but never on this scale. For their last quick-draw challenge they assemble on the parade ground to capture at speed a whole platoon of naval cadets marching in formation as they perform a sword drill. Ahead of the final ever challenge, Una travels to the Kent coast to learn what attracted JMW Turner to the seaside town of Margate and led to a lifelong fascination with the sea, while in his last how-to guide Lachlan gives tips on how to capture constantly moving crowds of people. With everything resting on the last challenge, the stakes are high and the sense of excitement even higher as the finalists create one last painting - capturing the light and atmosphere of an idyllic but visually complex scene - Dartmouth harbour. At the end of a gruelling and emotional six weeks, Daphne and Lachlan decide who should take the title and announce their first Big Painting Challenge winner. Show less
