TJ's christening turns grim when a body is discovered in the church. Jane almost abuses her power in order to protect Tommy when Lydia's fiancé, Stuart Stawbridge (guest star Jareb Dauplaise) threatens to take custody of TJ, and budget cuts cause tensions to run high around the department.
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.
