The intelligence unit is joined by SVU detectives Benson, Rollins and Amaro to solve the case of a pedophile ring.

The Intelligence Unit investigates Adrian Gish, the arsonist indirectly responsible for killing CFD paramedic and Antonio's sister Gabriela Dawson's friend, Leslie Shay.

They eventually find his real name, Trenton Lamont, and as a boy he was the only survivor of a fire that killed his entire family when he was 7 years old.

After a failed stakeout, they search Lamont's home in which they find numerous photos of Gaby and realize he's now targeting her.

Lamont lures her into a building where he traps her in an elevator and pours gasoline inside, intending to burn her and himself alive.
