Detective Laura Diamond (Emmy Award-winner Debra Messing) can't help that she's the smartest homicide detective in all of NYPD. She just... is. So smart in fact that she manages to solve the most perplexing of murders even while managing to raise two young boys as a single mom. Laura gets some help from her ex-husband Jake Broderick (Josh Lucas), who spent the last year as her boss at the Second Precinct, but, in the wake of a near-fatal injury and a power struggle, may have to return to the precinct in a different capacity. Laura's work life and personal life are forever intertwined, with her ex forever trying to win her back, which would involve prying her away from her very sexy new chef boyfriend, Tony (Neal Bledsoe).
