Erskine (Efrem Zimbalist Jr.) learns that Bishop John Atwood (
Dean Jagger), a peace envoy to the US, has been targetted for assassination. Unfortunately, the trigger man, known only to the FBI as "Anton Christopher", has never been photographed or fingerprinted, making it virtually impossible to track him down. Further complicating the situation is the fact that Christopher has been hired by one of Bishop Atwood's most trusted confidantes! ~ Hal Erickson, All Movie Guide
