Retreat (film)

Retreat is an 2011 British horrorthriller film and the directorial debut of former film editor Carl Tibbets. The film stars Cillian Murphy, Jamie Bell, and Thandie Newton as three people isolated from the rest of the world on a remote island, who are told they are survivors of a fatal airborne disease that is sweeping over the entire world. However, their induced isolation may be the result of a lie, and it may be that they are being held at the whim of a madman. The film has had mainly positive reviews.

Kate spends the next day waiting at the jetty for Doug to arrive, but to no avail. Later a mysterious man in green combat fatigues washes up on the island, bloodied and halfconscious. When he comes round, he identifies himself as a soldier, Private Jack Coleman Jamie Bell. He tells Martin and Kate that there has been an outbreak of an airborne disease, Argromoto Flu, codenamed R1N16, which started in South America and has spread over the entire world in the timespan of a few weeks. The virus is incurable and highly contagious, attacking the respiratory system and causing the victims to choke on blood with a 100 fatality rate. Jack says that the military has lost control, and is now advising civilians to seal themselves up in their homes and not allow anybody access. With only static now coming from the CB radio, Martin decides to play it safe and help Jack, who aggressively takes command, board up the door and the windows.Over the next few days, Jack becomes increasingly strange and erratic, and his intimidating behaviour begins to disturb the couple even further. They even suspect that the virus might not be real and Jack is insane. When Kate asks him if he is married, he tells her his wife died of R1N16 and he becomes aggressive and threatening. Martin and Kate decide to leave the cottage and take their chances outside, but Jack refuses to let them, forcing them into the bedroom at gunpoint and locking them in. Martin sneaks outside through a skylight, finding the bodies of Doug and his wife at the pier, killed by gunshot wounds. Using Dougs hunting shotgun, Martin returns to the cottage and gets the upper hand on Jack. However, just as Kate begins to tie Jacks hands behind his back, Martin suddenly begins coughing up blood it appears the Argromoto Flu is very real and he is infected. Kate is forced to shoot her husband dead with the shotgun, to spare him a slow and agonising death. ........
