Laura Diamond, a homicide detective with the New York Police Department, who balances her day job with her off-duty hours as a single mother to twin sons. Her rambunctious twin boys and soon-to-be ex-husband, Jake - who can't seem to find the time to sign the divorce papers - make life interesting. Complications arise when Jake becomes Laura's boss at the precinct, but with the help of her understanding - and attractive - partner, Billy, she somehow manages to make it all work.
