Actress Kyra Sedgwick (The Closer); singer Bret Michaels (CD, "Custom Built"); Jimmy Cliff (CD, "Existence") performs.

Dara O Briain and regulars Hugh Dennis, Russell Howard and Andy Parsons look back at another week's news with guests Patrick Kielty, Zoe Lyons and Milton Jones.

Andy’s undercover skills are tested – and found to be lacking – during a citywide campaign to clean up the streets, when she’s tapped to pose as a prostitute in order to arrest unsuspecting johns. But the real test comes when Andy and Dov inadvertently put a vulnerable street informant’s life in danger, and it’s up to the two rookies to infiltrate a dangerous gun deal in order to save the trapped woman from a group of ruthless criminals.

The behavior of Tucker's best friend causes him to suspect the worst, but Hank realizes a medical condition is to blame. Meanwhile, Divya treats a woman who fears her job as a winemaker is on the line when her symptoms hinder her palate.

Tonight's guests are actor Nicolas Cage and a performance by Marina & the Diamonds.
