Wild Cards

Wild Cards follows the unlikely duo of a gruff, sardonic cop and a spirited, clever con woman. Ellis, a demoted detective, has unfortunately spent the last year on the maritime unit, while Max has been living a transient life elaborately scamming everyone she meets. But when Max gets arrested and ends up helping Ellis solve a local crime, the two are offered the opportunity to redeem themselves, with Ellis going back to detective and Max staying out of jail. The catch? They have to work together, with each using their unique skills to solve crimes. For Ellis, that means hard-boiled shoe leather police work; for Max, it means accents, schemes and generally befriending everyone in sight, while driving Ellis absolutely nuts. Against the backdrop of beautiful Vancouver — with all its unique, charming, and even contradictory neighbourhoods and subcultures — the two will have to learn what it means to trust another person and maybe actually become partners.

The Handmaid's Tale

The Handmaid's Tale is the story of life in the dystopia of Gilead, a totalitarian society in what was formerly the United States. Facing environmental disasters and a plunging birthrate, Gilead is ruled by a twisted fundamentalism in its militarized ‘return to traditional values'. As one of the few remaining fertile women, Offred is a Handmaid in the Commander's household, one of the caste of women forced into sexual servitude as a last desperate attempt to repopulate the world. In this terrifying society, Offred must navigate between Commanders, their cruel Wives, domestic Marthas, and her fellow Handmaids – where anyone could be a spy for Gilead – all with one goal: to survive and find the daughter that was taken from her.
