Watch MasterChef Season 5 Episode 24 Online

Three contestants from the 2008 series are back to have another shot at the MasterChef title. But as they have been here before, things get tougher; this time they have to survive an 18-hour shift in professional kitchens. First they are off to Galvin at Windows at the Hilton Park Lane Hotel for breakfast service, and then it is straight to the Oxo Tower Restaurant for evening service. Only the best will go through to the quarter-final, where the four comeback contestants battle it out for the last remaining place in the semi-finals.
