Question: is the movie the guardian a true story

Answer: No, The mishap in The Guardian where Randall loses his crew is loosely based on an actual U.S. Coast Guard aviation mishap in Alaska. The aircraft was an HH-3F Pelican (USCG variant of the Jolly Green Giant) instead of the HH-60J Jayhawk (USCG variant of the Blackhawk/Seahawk) pictured in the movie.
