In one of the most memorable challenges ever on the series, three contestants go into a maze, given directions by a contestant via walkie-talkie and have to try not to get caught. Beverly directs Alan straight into the attackers and Abby goes well but Ben still manages to get caught. Rocky claims his machine wasn't working and he couldn't hear Jan's instructions, yet he somehow managed to make it to the end in a long time. Everyone suspects someone different. In one of the most controversial eliminations ever, Rocky goes. But later he claims Jan told him she was the Mole and told him that as long as he gave her a percentage of the winnings, he could vote for her etc. But it seems he was wrong. Jan of course denies to this day that she did that thing.

With only two men and five women left, the challenges get harder. Linda and Jan build a raft that the other five have to travel on without it going faulty but it doesn't work. And the boat the other five are on mysteriously runs out of fuel. Challenges are failing everywhere, but whose work is it? Beverly and Josephine have done well by not wasting money on a challenge where they could have gained an exemption but unfortunately Josephine leaves. She told Alan she was voting for him but he changed her mind and promised he wasn't the Mole.

The halfway point has arrived and the series has sorely tested the contestants. Each of them has to try and get to the red flag without being shot by snipers or their teammates. If only one person makes it, they get an exemption. Alan almost shoots Abby for it but he gets the exemption. As the group tries to solve riddles, Abby, Ben & Linda don't do too well. While photographing native species, several problems arise such as Abby taking a picture with the lens cap on.

The women fail at a task involving abseiling and Linda has to interrogate the group to find out what they did. If she is successful she gets a free pass. She breaks Abby down and gets the info and the exemption. Abby is acting extremely suspiciously, but who believes she is the Mole? Beverly is eliminated, leaving the four remaining contestants alone with Grant...

Linda saves the day when Alan and Jan fail at a sports challenge, Abby almost loses a photography challenge. In a game of roulette, Jan has to die her hair red, Abby has to have acupuncture and Linda is painted nude - something she regrets. Alan gets three tasks which are easy. It seems Jan suspects Alan, Abby suspects Jan, Linda suspects Abby and Alan suspects Jan. And Linda is the one eliminated.

Alan and Abby save one challenge when Jan fails it but all three contribute to another challenge. When it looks set that they have won the other, they discover Alan broke a road rule and the challenge is lost. Abby is fixed on Jan as the Mole, while the others blame each other. And finally at Port Arthur Jail the questions are answered. Jan wins $115,000. Abby steps out to look at the Mole - Alan.

Alan was the Mole. How could you have known? This special episode looks in detail at each episode and shows you the clues.
