The episode opens with panicked shouts and a child's voice pleading "Dad! Help me!" from behind a locked safe as oxygen falls. The captain explains most safes can be reset via the security question, and the team urges Allen to reset the password to save Ann. Allen refuses and is accused of staging it out of jealousy—"I'm dating Lisa." Lisa first claims Ann is with grandparents and calls the voice fake, but someone reveals Ann wasn't left there. With oxygen down to 1%, Lisa decides to call her parents to confirm Ann's whereabouts, leaving the rescue unresolved.
