A trip to the Coliseum in Rome sees the Saint helping out a young American woman from being fleeced by a local cab driver, Marco (Warren Mitchell.)
Next thing the Saint knows. He is waking up in a police cell. He was slugged and the woman was abducted.
She is the daughter of a US state governor Hudson Inverest (Alexander Knox) who is in Italy for some trade talks.
The kidnapper is mafia gang boss Tony Unciello. He wants the governor to release his brother from death row as he is due to be executed soon.
The Saint has only a few hours to locate the daughter with the help of Marco. Unicello has men everywhere so a doublecross is hard to do.
There is a great cast list here. Warren Mitchell as comedy relief. Oscar nominee Knox. There is some actual location shooting of the Coliseum.
The story itself is lacklustre with a few plot holes.
What a coincidence that the governor of the state where your brother is imprisoned in just happens to be visiting Rome. If the brother can have the death sentence commuted. Some smart lawyers could later get him out of jail on a technicality. So he must have had some not so smart lawyers to have a jury find him guilty!
