New York City, 1956: When 19-year-old Marion Brooks comes across an opportunity to audition for the Radio City Rockettes, she jumps at the chance to exchange her predictable future for the dazzling life of a performer. Meanwhile, the city is reeling from a string of bombings orchestrated by a person the press has nicknamed the “Big Apple Bomber." With the public in an uproar, the police turn to Peter Griggs, a young doctor who espouses a radical new technique: psychological profiling. As both Marion and Peter find themselves unexpectedly pulled into the police search for the bomber, Marion realizes that if she hopes to catch the culprit, she’ll need to stand out and take a terrifying risk. In doing so, she may be forced to sacrifice everything she’s worked for, as well as the people she loves the most.
