Host Vivienne is a straight-talking protagonist, like Sally Jesse Raphael, Ricki Lake, Jeremy Kyle and Dr Phil all rolled into one. But her ambition knows no bounds - she wants to be Oprah. Flattened by a blundering security guard on set following a punch from a guest, Vivienne is hospitalised and begins to question her future as a talk-show host - until her manic producer, Helena, reveals that ratings have doubled as a result of all the drama.
