According to the synopsis of the episode, "A dormant serial killer is suspected of resurfacing as Valentine's Day takes a deadly turn. Meanwhile, secrets of a romantic nature fill the squad room."

The killer is on the loose and the entire police department is on high alert. Though Laura doesn't know much of the killer, she suspects that she had encountered him in the past.

Elsewhere, it seems that two of the officers in the department will get involved with each other romantically. Though it is not yet revealed who the officers are, most probably Billy (Laz Alonso) will finally propose to Meredith (Janina Gavankar) and the two of them will become a couple.

In the previous episode titled "The Mystery of the Morning Jog," Laura and team investigated a Men's Rights group implicated in the murder of the city's top sports surgeon while Billy and Meredith took their relationship to the next level.

Earlier, a mysterious attacker tried to assault Laura on more than one occasion. However, she dodged the attacks every time. Though Laura knew well to protect herself, she had to find the attacker before he could have harmed her, or worse, managed to kill her.

Laura had certain reasons to believe that her attacker was the same person who killed perfume mogul Michael Dunham. However, while investigating the case, she came to know something about the killer's identity that left her completely shocked.

"The Mystery of the Dark Heart" will air on Feb. 10 on NBC.
