Can you explain the ending of the movie Containment?

The ending of the movie Containment differs between the two versions, so I will explain both. For the 2015 British film Containment, the ending reveals that the main character Mark, who has been trapped in his apartment building, discovers that the government quarantine is not just about a virus but about controlling the population, and he realizes that his wife was infected early on. In the final scenes, he attempts to escape the sealed building with evidence of what is happening, but finds that the outside world is also heavily controlled, and the film ends on a bleak, ambiguous note suggesting that containment is widespread and there is no real escape, emphasizing themes of isolation and government overreach. For the 2016 CW series Containment, the ending of season 1 provides more closure. It is revealed that the virus was engineered as a bioweapon by a pharmaceutical company, and the outbreak started due to a lab leak. The cordon is eventually lifted after a vaccine is developed, but not without major casualties, including the death of main character Jake. The finale shows Lex and Jana reuniting after being separated by the cordon for months, and the city beginning to heal, but with lasting trauma. The series ends with the message that containment saved the larger population at great cost to those inside, and it closes with a sense of bittersweet survival rather than a happy victory.
