Danny and Frank both face moral tests when work and home life collide to produce a pair of troublesome but very different personal dilemmas.

Frank pushes to have a cop killer brought to justice, but Erin drops the charges and releases the suspect due to lack of evidence.

When Erin's informant is murdered, she can't help but blame herself for the death and works to help Danny discover who killed him. Meanwhile, Frank deals with public backlash against an officer.
