Social experiment in which people go on the run. The fugitives arrive on a deserted beach with only a change of clothes and a small amount of cash, then plan their first move. Nathan and James try their luck at a private marina, while Meurig and Elinor attempt to smuggle themselves off the island right under the hunters' noses. When a gale hits the island, Shoba and Amarinder are forced to use a more conspicuous means of transport.

The hunters lie in wait for Katie and Liam at an abandoned ski centre. Sarah misses her children and hopes to see them at their weekly football session on her way to collect camping gear from a colleague. The hunters get a tip-off from a member of the public on the whereabouts of Shoba and Amarinder, and the Chief hatches an elaborate plan to reel them in.
