Rich Dotcom returns to the FBI when he needs help with a pressing issue.

A tattoo points the team toward a powerful collegiate secret society, but they can't infiltrate it without the help of one of its alumni...Rich Dotcom.

The team goes undercover on a movie set to stop a terrorist plot with unlikely backers. Roman blackmails Weller with a horrible secret about Jane.

Jane and her team must fight for their lives when Roman sends deadly assassins after them. Meanwhile, Patterson goes on a date, Reade contends with the O.P.R. inquisitor, Jane and Weller go to dinner, and Zapata attends a funeral.

A decoded tattoo leads the team to a mysterious cache of dolls which turn out to be vehicles for biological weapons being sent around the world and now to the FBI. Jane exploits the fear of the weapons to advance her own plan to recover Shepherd.

The murder of a best-selling true crime novelist sends Jane and the team on a hunt for a serial killer detailed in the author's final manuscript, which also features lightly fictionalized versions of the FBI team.

The FBI is hot on Madeline's heels as Jane seeks help from a familiar enemy.

Jane and the team reach out to Patterson's father in the hope of gaining access to a high-level conference in Finland where they hope to bring Matthew Weitz to their side.

The team scrambles to get ahead of Madeline and Ivy as they close in on the bunker's location, but someone on the inside is feeding Madeline information. As her plan takes shape, the team may be forced to take desperate measures.
