After the FBI discovers that the sex slave case is actually an illegal organ harvesting case, Patrick and Lisbon go after one of the group's suspected leaders before the latest group of kidnapped girls are lost.
Cho is investigating transplant clinics that might have used the organs of the girls and Patrick notes that their blood type is indicated on their feet. Ari and Ray Qasimi are stabbed to death in the prison and Wiley finds who owns the truck that was transporting the girls. Their prime suspect is Michael Ridley, but they have difficulties to find evidence to incriminate him. Meanwhile Pike presses Lisbon to go to Washington and she gives her final answer.—Claudio Carvalho, Rio de Janeiro, Brazil
