Being a detective is usually a safe job. Not anymore, for her.

Detective Blake Auley and her colleague, Matthew Torres, attend a ballroom party downtown Halifax, Nova Scotia, in hopes of catching a reported drug lord.

After Blake gets distracted during the investigation, their hopes of catching someone are eventually let down, leaving the party with empty handcuffs. Blake goes to take a quick restroom break, discovering her phone is missing.

She immediately rushes back up the staircase to retrieve her phone, unsuccessful when a group of people abruptly approaches and surrounds her, injecting a drug into her to sedate her.
