The candidates are summoned to Imperial College London, where Lord Sugar tells them that their next task is to design a piece of wearable technology. They need to combine up-to-date fashion with cutting-edge kit, before producing prototypes and pitching their products to retailers. The candidates get designing - one team dreams up a hi-tech jacket, the other a sweatshirt with a built-in video camera. Half the candidates focus on fashion, while the rest tackle the technology, but it is not long before there are crossed wires and mixed signals. On sales day the teams have appointments with some of the country's biggest retailers, but it is touch and go as to whether one team will have a product at all and a slip of the tongue threatens to tear a pitch apart. In the boardroom, Lord Sugar has a surprise in store as the candidates find out he is in no mood for excuses.
