Magnum, P.I. (1980)

Thomas Sullivan Magnum IV (Tom Selleck) is an ex-Navy "NIA" (ONI) Lieutenant, and Vietnam Special Ops veteran who resigned his commission at age thirty-three because he never got to be twenty-three. On the beautiful Hawaiian islands, Magnum is a P.I. who enjoys life, his buddies, and who works just hard enough to keep it real.
