In an effort to calm down Gabriel Wyath -- a patient who has threatened to blow up a mental hospital -- Britten is compromised, and the effects follow him into his other reality. Meanwhile, Rex introduces his girlfriend, Emma, to his dad and Bird shows concern over Britten's lack of focus due to his sleepless nights.

Detective Britten and Bird look into what appears to be a case of gang violence, but clues from his other reality force him to look a little closer. Meanwhile, Hannah uses her intuition to talk through a tough situation with Rex's girlfriend Emma. Later, Captain Harper finds herself having to take back a promise and Detective Vega is planning Britten's going away party.
