Rizzoli & Isles Season 7 Episode 8 focuses on a double homicide involving members of a biker gang. Someone -- probably a rival gang member -- shoots the two as they work on a motorcycle in their shop, and it's up to the BPD to figure out who.

This case has ramifications for everyone. Nina has to threaten a suspect with her gun in order to protect Frankie and has a hard time dealing with it, Angela is unhappy that Jane is going undercover, and Jane is realizing that everyone else's life is moving on.

When the lead witness refuses to talk but is reportedly ordering a hit from inside jail, Jane goes undercover. She disguises herself as a tough, dangerous inmate to get close enough to her suspect to find out who it is she's trying to eliminate. Along the way, she has to hide her fear, act tough, and get into a few fights.

Meanwhile, Angela struggles not to worry about Jane and the conclusion of this particular mission may change their relationship. Meanwhile, Frankie and Nina's relationship takes a hit as well because of Nina's guilt.
