Magnum plays Cupid's helper when he becomes involved with a former Russian pilot who has defected and a member of the Soviet track team in Hawaii for an exhibition match, plus various members of the dreaded KGB.

A person who goes by the codename of "Space Ranger" has tapped into Russian satellites and is giving information to the CIA. Once it is discovered that Space Ranger is one of Ralph's students (who the KGB is after), complications ensue.
