A routine deep sea diving mission in the North Sea goes terribly wrong when a young diver is stranded some 300 feet below the surface in the new film "Last Breath."

Based on actual events, the straightforward survival thriller Last Breath impresses with its attention to detail — specifically, in how it carefully locates the small, human moments in this life-or-death struggle.

In September 2012, while attempting to repair an oil pipeline off the coast of Scotland, the diving support ship Bibby Topaz lost control of the automated system of thrusters that held it in place above the repair crew.
