I was made in France and I’m pretty sure it was in French, and subtitled.  Wife has one-night stand with a guy who is subsequently murdered.  Except the guy who was murdered wasn’t actually the man she slept with.  Some identity-switching going on…  Wife owns dress shop, her husband is a lawyer. Murdered guy was client of the husband.  The husband-lawyer defends his wife (sort-of) when she is accused of the murder.  Plot of the movie is wife trying to find out exactly who she slept with and whose side her husband is on– and get the tape of the tryst from the apartment/villa manager where their rendezvous occurred.  It turns out –SPOILER ALERT– that the husband-lawyer and the guy’s widow were having an affair.  They killed the decedent and tried to frame the lawyer’s wife.  Betrayal on a grand-scale. Movie wasn’t too bad… it was watchable…
