Following a prison riot, several injured prisoners are brought to Mercy for treatment. Veronica finds herself sympathizing with her patient, but she's shocked to discover a dangerous secret he's been keeping. Chloe tries to convince her college football player boyfriend to take time off from practice to treat his head injury before it's too late. And, when Sonia's seemingly tough patient admits he's terrified to return to prison, she can't help but worry that she may be headed there too - unless she comes clean about her involvement in her former patient's suicide. Meanwhile, Briggs is confronted with a difficult decision that could jeopardize his career - or his life.
