Sanctuary: The Lost Season

is a side-story to the mainline Sanctuary series, focusing on darker themes and more controversial topics compared to the original lighthearted comedy/reality show.

is presented through episodes like traditional seasons but focuses less on the reality competition and is more a mix of the dark, twisted backgrounds of characters which have been exaggerated for the enhancement of this plot. The side story is set midway through the first episode of Sanctuary: Saints vs. Sinners, given the first episode titles being the same.

Premise
The Lost Season branches off during S2's premiere, where the cast discover that Banguerra Island is nothing but an artificial utopia constructed by the producers of the show to create a familiar tropical location to rival ratings by the likes of Love Island. Upon discovering this, the cast descends into chaos, inadvertently taking over the island for themselves while trying to escape from it. In order to save the show's producers from going bankrupt, the production team allow the rioting and chaotic behaviour in order to broadcast as a new show showcasing the cast's decline into madness.

As the show continues and the cast escape from the island, the 'newly arranged' reality show kicks in, as the producers prompt the cast that somewhere on the planet, one billion pounds has been hidden, creating a chaotic atmosphere as the teenagers frantically travel the planet in pursuit of this cash prize. On the journey, they will explore the warped reality of drugs, sex, heartbreak, and even death, if they want to have any chance of becoming the billionaire of their dreams.
