Coast Guard: Mission Critical S01E05 - Cliff Hanger

In Oregon, the United States Coast Guard Air Station crew navigate challenging elements and extreme shoreline terrain to extract a stranded hiker perilously clinging to the edge of a cliff. In the Florida Keys, Station Marathon personnel sharpen their climbing skills in a completely different way, when they are called on to rescue a man and his dog stranded overnight on a small remote island. In a bizarre plot twist, the man's wife--missing with their boat--becomes a person of interest.
