Erin and Anthony try to prevent the deportation of a prominent community activist, Coryna Garza, who isn't a citizen, and Frank must decide if the NYPD will participate in the U.S. Marshals' high-profile raid of a local gang.

When a key witness in Danny's case is killed just before testifying, Erin angers Danny by enlisting Anthony to help him find the killer. Also, Robert Lewis tries to force Frank to publicly support the Attorney General's investigation of the use of excessive force by police, and Eddie and Jamie get the call for an attempted suicide.
