The main story of the episode followed the discovery of Kathy Sullivan’s body, which pulled detectives Lena and Danny into Boston’s drug scene. At first, it looked like Kathy had died from an overdose, but finding her body in the harbor made it clear something more was going on. A new drug called “Killer Whale” connected her death to a dealer named Mitchell Edgars, known for his violent past.

The case became harder when Detective Brian Rodgers, Lena’s former partner, joined the team. His lingering feelings for her and their past made things tense between them and Danny. Still, the three worked through the conflict and followed the clues that led to Edgars, who had killed one of his own men to cover his tracks.

In the end, Lena and Danny caught Edgars after a tense showdown. His arrest cleared Kathy’s name and took a dangerous drug off the streets. The case was an important moment for Lena, pushing her to face her emotions and prove her strong commitment to justice.

While Lena and Danny were dealing with drug dealers, Jonah and Sean got involved in an unusual rescue. They promised an elderly neighbor, Mrs. Katz, that they would check on her missing friend.

When Murray didn’t come home, Jonah and Sean decided to break a few rules to find him. They followed the game’s clues and ended up at an old storage building, where they found Murray trapped under a heavy case. He was hurt and dehydrated but alive, thanks to their determination and teamwork.
