Coronet Blue

In an introductory sequence in the first episode, Frank Converse's character is aboard a passenger ship docked in New York, and is briefly addressed as "Gigot".

He discovers that there is a more pressing issue: he has been targeted for assassination by the same mysterious group that dumped him in the river.

[1]A man called "Gigot" by an assailant is pulled from a river, but has no memory of his past except two words--"Coronet Blue".

He is rehabilitated and gives himself the name "Michael Alden" and begins his trek to "find his past" but soon realizes he is targeted for assassination.

Anthony is lured to a strange apartment by a naval officer, where he finds a girl in a harem costume.

Alden makes arrangements to pay a man $2000 for his true identity, but both are pursued by ruthless hit men.

A troubled boy joins him hiding out in Central Park, unable to face home responsibilities after his father dies.

A reluctant girl is used as a medium in a magic act, and a blue coronet is part of her costume.

Alden hears a pop tune on the radio, supposedly from a dead singer, yet never released until that moment-but he somehow knows the lyrics already, and surmises that he had to have been present at the recording session.

In North Carolina, Alden is befriended by a cheery, ditzy blonde aspiring folk singer.

Following her leads to brutes, discovering he knows karate, a dojo instructor who mentors him, confused and cleared memories, with a martial arts finish.
