Erin and Frank
When an armed robbery ends with the death of a police officer, Frank (Tom Selleck) makes it a mission for the NYPD to bring the suspect to justice. However, tensions run high in the Reagan household when Erin (Bridget Moynahan) drops the charges and releases the suspect due to lack of evidence, on the fourth season premiere of BLUE BLOODS, Friday, September 28 (10:00-11:00 PM, ET/PT) on the CBS Television Network.
