Maggie Mars is a struggling screenwriter whose big break is happening now. Her latest script is being filmed and Maggie's on the set. But Maggie thinks that the lead actress is playing her character all wrong and tells her. A screaming match ensues.
So when said actress is found dead with her head bashed in with her own Oscar, Maggie is viewed as a "person of interest". She tries to keep a low profile and cooperate with the police. Complicating things is the fact that one of the deputies on the case is a former lover of Joe Camanetti, the sometime/longtime love of Maggie's life.
And somewhere out there is a killer who thinks Maggie is just too clever for her own good.
Memo #312 to Maggie: Never write murder scenarios too good for a killer to pass up...
