On-screen, she's Dr. Willoughby, a compassionate surgeon who saves lives with skill and a scalpel. Offscreen, she's Donna Sinclair, a ruthless actress fighting to control her fading career and the sleazy daytime hospital soap in which she stars. Joanna Lumley (Absolutely Fabulous) is deliciously bitchy as the aging, vain Sinclair in this hilarious send-up of British television. She'll stop at nothing to keep her place in the spotlight, from betraying her fellow actors to terrorizing her producer, pilfering toilet paper from the supplies closet, and lying her way out of a charity gig. As the conniving, vindictive, and utterly insincere Sinclair, Lumley steals every scene.
