The thriller was about an epidemic that breaks out in Atlanta, leaving the large city quarantined and those stuck on the inside fighting for their lives. The show only averaged 1.8 million viewers and a 0.6 among adults 18-49. Containment was sometimes billed as a limited series. But like other high-concept broadcast dramas started with the short-run premise — like CBS’ Under the Dome and Fox’s Wayward Pines — Containment had an easily expandable format — if the show were a success.
