Dr Julie Rees is working in the ER in downtown Vancouver when calls of an emergency come in - five teenagers have overdosed. Three died at the scene, two are in cardiac arrest and on their way to the hospital. It's a race against time to try and save them, one that seems impossible to win. Someone has synthesised a new drug out of Fentanyl, and the body-count is soaring... Fast-paced, tense and authentic.
