Having solved the Hawaii case rather quickly, they get called back to Boston early to handle three different cases that popped up in Boston over the Christmas Holidays. They leave Hawaii early and head back to Boston to solve a multitude of cases ? and in doing so, uncover an ugly dark secret that would forever surprise them about their beloved Boston Police friends. Throughout it all, they learn a bitter lesson about blind trust.
