Adorable Menteuse is a mild French comedy starring Marina Vlady. She plays a garrulous 18-year-old girl who can't go five minutes without telling a lie. When she falls in love with an older man (all of forty!), she vows to reform and speak nothing but the truth. But Vlady's reputation precedes her, and as a consequence her gentleman friend refuses to take anything she says seriously. Adorable Menteuse has also been issued under the title Adorable Liar.
