Plot

Frank pushes to find evidence against a suspected cop killer who shot one of Henry's fellow officers years ago. Meanwhile Danny and Baez investigate a string of murders involving adult film stars.

Danny is investigating a murder committed by someone wearing a mask. When he discovers the person has killed again, he learns that both victims have ties to the adult film industry. They talk to their boss who tells Danny that a girl who tried to join the industry committed suicide and her family blames the industry for her death. Frank attends the promotion ceremony of various officers and when he meets the father of one of them, he can't help but think the man is familiar so he detains him and learns he's a man who's wanted for killing a cop almost 40 years ago. And Henry was the one who initially investigated and then passed it to Frank who then passed it to Danny. The man denies killing the cop. But they decide to press charges and when Henry talks to Erin, he mixes up details which makes Erin want to plead the case out which Frank doesn't want to. Jamie and Jenko arrest a man who struck a girl with his car. He confesses to hitting the girl. But Jenko finds a witness who says the man was not driving. When Jenko talks to him, he denies it and the detective in charge refuses to entertain her suspicions.—rcs0411@yahoo.com

Immediately after promoting model cop Brent Miller, chief Frank orders the arrest of his father, which he recognizes as Donald DeCarlo, the elusive sole suspect of a cop murder from Henry's days, but his credible plea of innocence deserves due proof, which only be obtained by heartbreaking loyalty conflict. Jamie and Eddie prevent the mob lynching of Ted Santiago, whose car accidentally hit a child, but duly doubt his confession, unlike their bitch supervisor, unorthodoxly working trough a family drama.—KGF Vissers
