Returning: Sanctuary

ABC2 tomorrow begins the fourth and final season of Canadian sci fi series Sanctuary.

The series, starring Amanda Tapping, was recently confirmed as not being renewed for a fifth season.

The season four premiere of Sanctuary picks up where season three left off, with Helen Magnus (Amanda Tapping) standing on a cobblestone street, far from her own time or the modern Sanctuary resources. Having followed her long-time nemesis Adam Worth (Ian Tracey) through a collapsing time vortex, she is stunned to realise they have both travelled back to London… 1898. Worth is determined to change the course of his own history in order to save the life of his daughter – even at the risk of destroying the entire future – and Magnus must track him down and stop him before he can make changes too large to remedy.

Magnus’s dear friend James Watson (Peter Wingfield), history’s greatest detective and the inspiration for the fictional Sherlock Holmes, deduces the truth about her mission, and together they must find a way to stop Worth. But Victorian London contains unexpected pitfalls for modern-day Magnus, who’s frustrated by the return to a time when so many doors were closed to her. Crossing paths with her own past self, and with her star-crossed lover John Druitt (Christopher Heyerdahl) – otherwise known as Jack the Ripper – Magnus is at constant risk of unintentionally altering the timeline. And with someone murdering women in Whitechapel again, a decade after the original Ripper killings, Magnus knows more than she wishes about both the future and the past.

9:25pm Tuesday June 5 ABC2.
