Scriptwriter Keith Tutt fell in love with the work of French post-impressionist painter Edouard Vuillard in his school art class. When a large oval picture by the artist appeared in a provincial auction house he gambled his savings on it - even though it doesn't appear in the official record of Vuillard's works. To prove this is a Vuillard, the team will need to convince some of the most demanding art experts in France - and they've got a tricky history with the FAKE OR FORTUNE series. The quest for evidence starts in Geneva, where Philip and conservationist Aviva Burnstock compare Keith's picture with a huge Vuillard work called Le Grand Teddy, painted for a French cafe in 1919. Can science prove that the two pictures were painted using identical materials? Fiona picks up the provenance trail in France and Holland, unearthing tantalizing clues about the picture's past, while a meeting with a pair of British antiques hunters dramatically expands the scope of the investigation. Once the team has marshaled all their evidence, it's time to seek the approval of the Wildenstein Institute in Paris - the body who notoriously rejected a highly credible Monet in the very first episode of FAKE OR FORTUNE. Have the team done enough to convince them that Keith's picture is genuine?
