Previously on Blue Bloods Season 3 Episode 10 "Fathers and Sons", When two motorists driving gas-guzzling cars die at the hands of a sniper, Danny and Kate are put on the case of what the city believes is the work of a radical environmental serial killer. Meanwhile, a bicycle accident sends Danny's son Sean to the hospital with a life-threatening injury.
On this week's Episode title "Front Page News", Jamie must deal with the emotional consequences of his actions on the job. Meanwhile, Erin questions Mayor Poole on the witness stand.
The series follows the Irish-American Reagan family of police officers with the New York City Police Department (NYPD). Francis "Frank" Reagan (Tom Selleck) is the Police Commissioner. He was a U.S. Marine and a Vietnam veteran before he joined the NYPD. He is a widower whose son Joe died in the line of duty, leaving him three remaining adult children—Danny, Erin, and Jamie.
Danny (Donnie Wahlberg) is a top NYPD detective, holding the rank of Detective First Grade, but is sometimes hard-nosed and does not always go by the book. Danny is also a Marine veteran, having served in the Iraq War. Danny's partner is Detective First Grade Jackie Curatola (Jennifer Esposito). Erin (Bridget Moynahan) is an assistant district attorney in Manhattan who prosecutes many of the criminals Danny arrests. Jamie (Will Estes), Frank's youngest child, is a recent graduate of Harvard Law School and is a rookie officer on the police force after graduating from the police academy. Henry (Len Cariou) is Frank's father and the former NYPD police commissioner, now retired. Henry served in the United States Marine Corps during the Korean War. Henry often provides advice to his son and grandchildren. The family is close-knit; each episode includes a scene wherein they all have dinner together with their spouses and children and discuss their current cases.
Frank's middle son, Joseph, was an NYPD police detective who died in the line of duty. Joe was involved with the Federal Bureau of Investigation (FBI) investigating a group of dirty cops, who were operating within a fraternal organization called the "Blue Templar". Joe was murdered by these dirty cops when his covert investigation into their corruption was getting too close.
A running thread through the first season is Jamie's picking up Joe's investigation. The FBI tried to recruit Jamie, but he instead conducted his own covert investigation into Joe's death. Joe's murderers try to kill Jamie by tampering with the brakes on his car, but fail. Jamie then informs his father Frank, his brother Danny, and his grandfather Henry about his suspicions after the attempt on his life.
Along with Erin, they join together and complete Joe's investigation of the Blue Templar. After gathering sufficient evidence to obtain arrest warrants, Frank leads a team of police officers, including Danny and Jamie, and they arrest all the corrupt cops at a covert meeting while the dirty cops are dividing up stolen drug money. A detective named Sonny Malevsky (Michael T. Weiss), who was leading the gang of dirty cops, admits to killing Joe, but Malevsky commits suicide with his own service pistol after confessing to the murder.
Jamie was engaged to Sydney (Dylan Moore), a fellow Harvard graduate who broke off their engagement after he became a cop. Erin is divorced and has one teenage daughter, Nicki (Sami Gayle). Jamie's field training officer is Sergeant Anthony Renzulli (Nicholas Turturro), who is tough but fair with Jamie and thinks Jamie is one of the best cops he's ever seen.
