The firm of Bailey&Spencer is hired by no less than the Federal government to guard playboy/diplomat Ray Danton. Danton is an internationally known party
animal who is rather obviously based on Porfirio Rubirosa.
The thing is that regular security won't due because Danton shoos them away.
The trick is to make sure he doesn't know you're security and to keep up parting
with him. And like the real life Rubirosa, Danton likes to party.
There are people out to get him although we never really know why. The last
half of the episode has Efrem Zimbalist, Roger Smith, and Edd Byrnes all on a
yacht at a blow out keeping an eye out for assassins.
Danton does an outstanding job in his role, though the real Rubirosa wasn't
that silly in life.
