When cops are called to the home of Nick (guest star Michael Enright) and Amy Libergal (guest star Amy Benedict), they are surprised to discover two Russian men armed with guns and Nick dead in his bathtub. While Winters and Jaruszalski work to trace the men back to a ringleader, the case takes an unsuspecting turn when a second crime comes into play. Meanwhile, DDA's Dekker (Terrence Howard) and Stanton (Megan Boone) must move quickly in order to get their key witnesses to testify before they are extradited back to Russia.
