This lively adventure story stars Hugh O'Brian as Hugh Lockwood, a.k.a. Probe 1, an agent working for World Securities Corporation,who is hot on the trail of The Entourage Collection--nine diamonds valued at 22 million dollars which haven't been seen since 1945 (until now). Accompanied by Streeter (Sir John Gielgud), a diamond expert, Lockwood encounters intrigue-as well as romance with lovely Elke Sommer-while trotting around the globe looking for the diamonds. This was the pilot film for the short-lived but highly popular TV series "Search" (1973-74) which also starred O'Brian.
