When high-profile reporter and Frank's old flame, Melanie Maines, is almost assaulted while in town to investigate a controversial story, Danny and Jackie track down her would-be attacker to one of her cyberstalkers. But when the man's alibi checks out clean, Danny realizes that someone closer to Melanie, and carrying a grudge, could be behind the attack -- her own producer. Meanwhile, Jamie learns from Bianca Sanfino that Johnny Tesla is dead and whoever is behind the attack might try to lay it on Jamie. After Bianca goes off the grid, the Sanfinos confront Jamie and close in on him, but before things turn deadly, the cops stage Jamie's arrest and thus end his career as "Jimmy Riordan."
