The second group of five chefs face two tough tests set by Monica and Marcus. In their first challenge, the chefs travel to one of London's most exclusive addresses, the French ambassador's residence. Marcus and Monica set them the task of cooking a three-course fine-dining menu from a selection of the finest French ingredients for the ambassador and her special guests. The chefs must work as a team to come up with perfectly-executed dishes worthy of the gastronomic connoisseurs, including the ambassador's chef de cuisine. The chefs then return to the MasterChef kitchen where they must set their friendships aside and battle for their place in the competition. Just 90 minutes and one showstopper dish is all that stands between the chefs and a place in the semi-finals. After tasting all five dishes, Monica and Marcus decide whose time in the competition is finally up and which four chefs will move forward.
