The global environmental thriller is set in the present day, where anomalies and unnatural behavior in marine animals are causing upheaval all over the world. The Swarm follows a global group of scientists who come together to tackle one of the biggest challenges mankind has ever faced. They make the chilling discovery that deep at the bottom of the sea resides a collective intelligence which has suffered the ravages of civilization on its habitat - and decided to fight back.
The show centers on a fictional American pope, Pius XIII, born Lenny Belardo, who becomes the most conservative leader the Catholic Church has ever seen. Stubbornly resistant to the Vatican courtiers yet full of compassion toward the weak and poor, he faces the prospect of losing those closest to him - even his God.
