Shades of Casablanca. Dick Powell is Vincent Powers an American night club owner with a dubious past.
He is also involved in gun smuggling and selling them to various faction involved in the France/Algerian war.
These factions want the guns from Powers who is happy to sell to the highest bidder.
Inspector Boulanger is on his tail but Powers is distracted and falls for a visiting American in Paris.
She is Alice Wood (Jane Powell) who helps Powers out over a suitcase. As she is travelling alone, Powers shows her the sights including the view from the Eiffel Tower. Both fall for each other.
Powers unwittingly places Alice in danger as the gun runners target her.
A rather cynical story, part noir and the Rick Blaine influences are obvious.
Jane Powell died in September 2021. I presume she would had been the last remaining cast member alive.
