A frustrated writer helps save a woman being railroaded by the law -- or is she? -- in this comic mystery with romantic overtones. Phil Blackwood (Tom Selleck) is a best-selling mystery novelist who has run into a bad case of writer's block. Hoping to find inspiration for his next book, Phil goes to the city courthouse and witnesses the arraignment of Nina Ionescu (Paulina Porizkova), a beautiful Romanian immigrant who is accused of killing a man with a pair of scissors. For Phil, it's love at first sight, and after sneaking into jail disguised as a priest, he makes her an offer. Phil offers to let her stay at his house, and he provides her with an alibi -- she can claim that she couldn't have committed the crime, because she was with him at the time of the attack. Nina agrees, but after Phil encounters a handful of dangerous foreign agents, Nina's acrobatic parents, and a highly suspicious district attorney, he begins to wonder if Nina might have committed the murder after all. Her Alibi also features William Daniels as Sam, and James Farentino as Frank Polito; the song "Falling In Love" was written and recorded for the film by Randy Newman.
