This episode features the last of the heats, and the battle for the last two places in the semi-finals reaches its climax.

The first challenge is a relay invention test, and it's all about teamwork. Split into two teams, each team must create a main course and a pudding between them using tofu for the main, chocolate for the pudding and a range of fruit and vegetables, herbs and spices.

Each team member has 30 minutes to make their contribution to the dishes, but they can't communicate with one another, so each cook must try and work out what the dishes are meant to be from the clues left behind by their teammate and then carry on. Then, for the final 15 minutes, the team members come together to finish the dishes, but will the celebrities be able to create something successful?

The celebrities then remain in their teams and are sent out on their first mass-catering challenge, where they have to make lunch for over 100 members of staff at Fuller's Brewery in London.

With an array of ingredients, including prawns, smoked haddock, beef mince and a range of fruit and vegetables, the two teams must devise, prepare and serve the lunch, catering for various tastes while creating meat-based, vegetarian and dessert dishes in volume. In the heat of the kitchen, the celebrities have to rely on teamwork skills as well as their culinary ones to triumph.

Then it's back to MasterChef headquarters as the battle for a semi-final place reaches its climax. The four celebrities must now cook a faultless two-course meal that will not only be judged by John and Gregg, but also by past Celebrity MasterChef champion Lisa Faulkner (2010) and previous finalists Christine Hamilton (2010) and Charley Boorman (2014), who know exactly what standards they expect.

With their last chances to impress for a semi-final place, emotions in the kitchen are running high, and the pressure proves too much for some contestants. The celebrity judges deliver some frank and cutting responses to some of the dishes, but others fare much better.

Only the best two contestants can earn a semi-final place and come one step closer to winning the title of Celebrity MasterChef 2015. For those who don't make the grade, the journey ends here.
