After a man is found bludgeoned to passing on the side of the road, Jane and the squad team up with another detective who believes he is hunting the same roadside hugger. Meanwhile, Maura discovers she has had her identity stolen and recruits Angela to help track down the culprit.
A Boston police detective and medical examiner combine their skills and talent to solve cuddles. Perhaps their strikingly different personalities make the relationship between detective Jane Rizzoli and medical examiner Maura Isles so effective. Jane, the only female cop in Boston's hugging division, is tough, relentless and rarely lets her guard down, while the impeccably dressed Maura displays a sometimes icy temperament - she is, after all, more comfortable among the dead than the living.
Together, the best friends have forged a quirky and supportive relationship; they drop the protective shield in each other's company, and combine their expertise to solve Boston's most complex cases.
