Harriet and Douglas conspire to escape when they discover a dinghy. But their best-laid plans are soon disrupted as Douglas starts to make promises he can't keep.

Brett and Arnab decide to find out what Harriet is hiding in her case, while Susan attempts to seduce Douglas, armed with an inhaler and her knowledge of the 50 Shades of Grey trailer.

Douglas discovers that a nearby island is inhabited and wants to visit, but Brett, desperate to stop him leaving, puts him on trial for 'assaulting' Susan. Meanwhile, Arnab attempts to convince Susan that having sex with him will make Douglas jealous.

Douglas and Brett set sail for the other island and what they discover changes everything. Harriet and Susan discover Arnab's secret stash of chocolates while he relishes being 'King of the Island'.

After Brett's miraculous return he learns of Harriet's large inheritance and uses the information to his advantage. Douglas is banished from the camp, but the group is promised salvation.
