A new group of teams takes off from Long Beach, California on two flights to Lima, Peru. The new teams include "Survivor couple" Rob and Amber, son and mother Susan and Patrick and pals Ryan and Chuck, among others. Once in Peru, the teams follow clues taking them many miles to various destinations and exploring the country and its mountains. Tasks include riding ziplines and traveling by several forms of local transportation. Several teams fall behind after carelessly not searching carefully before locking in times on a task that put them behind the rest of the pack. Many teams express a desire to outfox, outwit and outrace Rob and Amber. A Detour, Rope a Llama or Rope a Basket, gives teams a choice of either leading llamas into pins or carrying heavy baskets two-thirds of a mile. Some teams struggle with the llamas, while other teams breeze through their chosen task. A true photo finish of mere seconds sends one team home.

Two girls had been fired in the first two weeks. "We're too good for them", boasted Raj. But Sir Alan Sugar had decided to reorganize the teams for the third week. "Matthew, I'm gonna make you the team leader", he boomed. Matthew looked gobsmacked. Adele was also chosen as a Team leader by Sir Alan Matthew, Raj, Paul and James were joined by Saira and Rachel for team Impact.Adele, Miranda and Miriam were joined by Ben, Sebastian and Tim for team First Forte.Their task: to buy a range of products including a diamond, a bottle of champagne, jellied eels, a bowler hat, a Freeview box, a dental check-up - and get back to the boardroom by 5.30pm. Adele gave each team member a job description. Miranda was not pleased to be appointed Adele's PA and ordered to take notes of meetings. James knew exactly where to buy a bottle of Bollinger 96 Grande Ann... e. He took the team off to the expensive Lea and Sandeman wine merchants in the Fulham Road - and paid ?49 for a bottle. Tim found a cheaper shop and only paid ?44.90. Rachel must have been pleased to learn she needed two fillings in her dental check-up. Sebastian has perfect teeth. Raj and Saira sweet-talked a shopkeeper in Punjabi - and walked out of the shop with a Freeview box which cost them nothing! Matthew's team won despite failing to buy a bowler hat and his team were treated to dinner with Sir Alan at his favourite Italian restarant. Adele's team all blamed the team leader. Sir Alan was reminded that he always got the blame as the boss for everything that went wrong at Tottenham Hotspur FC "and I didn't even play!" Miranda and Ben were chosen to join Adele the next morning in the boardroom. Miranda and Adele kept squabbling in front of Sir Alan - "bickering like two old washer-women" - until Miranda was fired. Sir Alan thought she should have shown more respect for the team leader.
