Frank Converse's character (called "Gigot" or "Chico" in the first episode), is told by a woman and two men that they know what he is up to, after which they drug him and dump him in the river. He manages to pull himself ashore and the only words he says are "Coronet Blue". Suffering from amnesia due to the effects of the drug, he soon discovers that he has been targeted for assassination by the same, mysterious group of killers. He adopts the name "Michael Alden," a combination of the name of his doctor and the name of the hospital where he was taken to recover.
