The story follows Danny (Donnie Wahlberg) investigating a murder and needing to turn to the help of his father, Frank (Tom Selleck), to get information on the case. His search then leads him to ask Erin (Bridget Moynahan) for assistance, and she's able to point him in the right direction. As the episode reaches its climax, the man accused of murder holds a courtroom of people hostage, including Erin and her ex-husband.
