Jaw-dropping surprises keep piling up for survivors of the late bigamist  Colin Walcott, whose two very-different daughters discover at his funeral that they’re half-sisters.  Just as Catherine and Cat adjust to their awkward reality, another half sibling from another mother widens the family circle.  If Catherine and Callum had known they were related, they wouldn’t have shared an amorous moment.  Enjoy more fun and fallout as their father complicates their lives from beyond the grave.  “A very funny, oddly tender and moving exploration of love, grief, forgiveness and family”—The Guardian.  6 episodes.  2 1/2 hours on 1 disc.
