It's New Year's Eve but obstetrician Dr. Tara Ross isn't celebrating. After a catastrophic delivery, Tara, a workaholic who's sleep deprived, and already stressed to the max, lapses into a post -traumatic memory loss. Wandering the streets of Manhattan's Upper West she is mistakenly swept up in a narcotics sting operation and lands in Jeffrey Corrigan's precinct.

Divorced but married to the job as a dedicated homicide squad commander, Detective Lieutenant Jeffrey Corrigan has his hands full chasing a sadistic drug czarina, and now murder suspect, with ties to his corrupt captain. The last thing he needs is another woman to complicate his life. That is until he encounters Tara in the precinct's holding cell.

Unable to drive her home during a blizzard, he has no choice but to bring her to his house. As a temporary guest in his home, Tara and Jeffrey build a relationship they'd both like to make permanent. While enlisting the help of the precinct psychiatrist to restore Tara's memory, he fears for her safety when threats mount against both their lives. The evil drug czarina and her cadre of corrupt cops will make him pay for nosing around in their business. They'll start with Tara.
