"Blue Bloods" Season 6 will air its 10th instalment, “Flags Of Our Fathers,” on Friday at 10/9c on the CBS Television Network. It will showcase the Reagans, specifically Frank (Tom Selleck) and Danny (Donnie Wahlberg), as they are both forced to make a difficult choice between standing by what they believe in and following the law.

The episode will also feature the other members of the Reagan family, including Erin (Bridget Moynahan), Jamie (Will Estes), Henry (Len Cariou), Sean (Andrew Terraciano), Linda (Amy Carlson), Jack (Tony Terraciano) and Nicky (Sami Gayle). [Spoiler Alert!]

According to TV Guide, “Flags Of Our Fathers” will show Frank being put in national spotlight as he deals with a planned rally by a radical anti-government group. The activists are planning to burn the American flag, and Frank has to choose whether to stop the demonstration or adhere to the parameters of free speech.

In the episode preview, Frank is seen opposing the group’s move, saying: “Only fools seek peace by inciting violence.” However, the clip shows he will acknowledge that the activists have certain rights.

Meanwhile, Danny will face major interrogation by the District Attorney’s investigator when his former partner gets accused of planting false evidence. Danny wants to trust his ex-partner, but mounting evidence support the D.A.’s accusations that the homicide investigation was done in haste, and evidence was planted to wrap up the case, which resulted in putting an innocent man behind bars.
