As the only female member of the crime team, Jane (Angie Harmon) is not inferior to her shrewd and capable male colleagues. For Jane, nothing is more important than being vigilant at all times. Her energy seems to be fighting the whole world. Maura (Sasha Alexander) is an experienced forensic doctor. Compared with staying in the lively and lively world of the living, she is shy and introverted and prefers to enjoy the leisurely afternoon with her "corpse partners". It is such a "weirdo" in the eyes of ordinary people. Maura and Jane have become friends and partners at first sight. One of them is "outside" and the other is "inside". They have jointly solved many incredible cases and become a good story in the industry. At the same time, outside the workplace and in life, there are also various difficult problems waiting ahead.
