When cartoonist Zoe Foster stumbles across a woman's lifeless body in an alley beside her New York office, she does what any good, civic-minded citizen would do: she calls 911. But when the police arrive, there's one small problem -- the woman is gone. Without proof of foul play, the police dismiss her concerns, but like Kitty Floyd, P.I., the heroine of her popular comic strip, Zoe is not easily discouraged. Her curiosity is piqued even further when she learns that the missing woman, Lola Malone, was a singer at Blue Moon, a nightclub owned by Zoe's ex-husband. Trying to set aside their differences, the two team up in an effort to find Lola. But the search turns hazardous when Zoe comes up with a new story line based on the singer's disappearance, and immediately she becomes a killer's target. All evidence points to one of her fans, someone who will do whatever it takes to stop Zoe from finding out the truth.
