Alisha Danniels is left fighting for her life when she is hit by a speeding car after being taken home from the station. A chase ensues, but the car escapes down railway lines before being found on fire. With the fire quickly extinguished, there is hope for the investigators. The car leads to two investigations as Roberts and Keane try to track down a teenager who fooled the owner in order to car-jack him. When the boy's older brother leaves mid-interview, Alisha identifies him as the driver of the drive-by car. Refusing to give a statement, Dasari and Smithy discover Alisha's dad Oscar knows where he is. As part of the forensic check of the car, bullets are found in a hidden compartment of the boot, so Carter tracks the owner in order to bust him selling them on.
