Peter and Nicola make a plan to signal from the lighthouse to any passing ships. Nicola and Ginty pretend that Peter has drowned, trying to escape from the lighthouse so that he can hide without Foley coming to look for him. Foley seems genuinely upset about Peter and is kind to the girls. Later that night, they signal SOS, watching the Naval fleet go past without seeing them. However, they persevere and eventually are spotted by Anquetil. Foley comes up the stairs when they are signalling but Ginty throws her lamp at him and he is seriously injured.
