Chris Eubank is still not happy, this time it's due to Gazza telling a story about spending nine hours on a plane next to a dead man. In another challenge, the celebrities are asked `What's in the Box?" as they try to identify a Cumberland sausage, gherkins and a rabbit in complete darkness.

The bunker is taking its toll on the celebrities as the competition nears its end. They face an electrifying challenge involving pitch-black orienteering and painful shocks. Max makes some emotional revelations.

Danny Dyer presents the final of the pitch-black contest, which sees the celebrities more reliant on each other than ever.
