Sun and Sky, the horse favored to win the Kentucky Derby and possibly the Triple Crown, is being shipped to Kentucky to participate in the upcoming race. During the flight, however, all four members of the cargo plane's crew are overcome by some kind of drug, though the pilot manages to radio a distress call before losing consciousness. Mannix is hired by the insurance company holding the policy on the missing horse to investigate what happened. His search turns up the missing plane, and all four unconscious men, but not Sun and Sky. Mannix discovers that at least two of the men might have had a motive to steal the horse -- and then receives a confession from the horse's owners that they, too, are having financial problems that would make them suspects as well.

When Mannix (Mike Connors) goes to investigate the horse farm where he believes the stolen horse is being held, he parks some distance from the buildings and slips across a horse enclosure to approach the buildings unseen. The sun is coming from a low angle as he does so, making his shadow across the enclosure lengthy; but when he reaches the buildings, the sun is suddenly overhead and his shadow is cast beneath him.
