The trauma team battle to save the life of a patient with a fence post impaled through her face, and Fiona's world is turned upside down when Glen Boyle joins the team as their new trauma consultant.

Despite being haunted by his army past, Glen leads the trauma call on a man who has been severely beaten. A curious serial number branded onto the patient's skin indicates he's a slave labourer who has been illegally trafficked.

A mentally disturbed patient sustains severe head injuries when she jumps from the balcony in the hospital's atrium. Glen drills into her skull to relieve the pressure on her dangerously swollen brain. Harry recognises the woman as a regular patient she had discharged from the ED the night before, but keeps this a secret.
