This film explores the strange story that happened when the world's water supply ran out dangerously. In order to get a lifeline, a small group of survivors turn to the only clean source of water left, but things are on a very bad course. Visitors sneak into their boat at those moments where they will soon be in a real test of their lives.
The film rattles along nicely towards its inventive final stand-off, which once again makes the most of the relatively limited resources through ingenious use of some chains, an aeroplane wing and basic physics.
