Andrea Zuwowski has never taken life too seriously. Up until last year, she spent most of her time on men and activities that would anger her strict Trinidadian born mother. She even joined the NYPD specifically because her mother forbade it. Because of her initial lack of respect for the job, Andrea has been stuck with the worst duties the NYPD has to offer. Lately she’s been trying to change, but just can't get a break at work or in life. Stuck directing traffic, living at home with her family, and constantly meeting the wrong men, Andrea wonders if life will ever change.

Then one day while on duty, she comes across a bizarre man in a black hood claiming to be a ninja detective. In reality he is Stanley Kidderick, a man who had the life he built taken away from him six months ago. Stan was fired after five years as head programmer and divorced by his wife after finding her in bed with another man. He coped by convincing himself his life was destroyed because he was meant to fight crime as a ninja detective. To hide from his pain, Stan wears a ninja mask and focuses his energy on his private investigation business.

Intrigued by Stan's oddness, Andrea pursues him and the two develop an initial spark. Meanwhile Stan has been working the biggest case of his life, bringing Erik Wrathborne, New York's most notorious and elusive burglar, to justice. Stan has uncovered Erik's hidden location and asks Andrea to help him as he attempts to catch Erik in his own warehouse. Against her better judgment Andrea decides not to miss this chance for the ultimate bust and agrees. The pair breaks in and is separated when Stan is taken captive. Inspired by Stan's confidence in her, Andrea saves the day by rescuing Stan while catching Erik and finding the evidence to put him away.

At the conclusion of the story, Andrea and Stan realize that during their time together, their spark has developed into something more. Against his wishes, Andrea finally gets to see Stan’s face while rescuing him and calms his fears about not having his mask by kissing him. Andrea receives a promotion at work and Stan is able to take off his ninja mask... for short periods of time.
