The search for Lord Sugar's next business partner begins, with the hopeful candidates getting whittled down over the next 12 weeks until only one remains. To demonstrate just how much is at stake, Lord Sugar summons the aspiring entrepreneurs to his boardroom, where he has a big surprise for them. Under the scrutiny of Karren Brady and Claude Littner, the candidates are put to the test with their first task, which sees them manufacturing burgers. They have just one day to turn their meaty burgers into a healthy profit by selling them to hungry Londoners. Chaos in the kitchen throws one team into disarray as they struggle to make the burger mix, while the other team waste precious time overanalysing the labelling. Trying to maximise sales, each team set up stalls to sell cooked burgers, but personality clashes and a poor choice of selling location threaten to derail the sales. In the boardroom, the candidates face Lord Sugar for the first time and someone becomes the first to be fired.
