Imagine if, every time you woke up, reality had changed in a crucial, heartbreaking way? That's the daily grind facing Michael Britten (Jason Isaacs) in this intriguing drama. After a car accident killed his wife - or was it his son? - the detective is living two parallel lives. In one, his wife survived the accident, in the other, his son. As he struggles to decide if he's now the cat in Schrodinger's box, he finds his two perspectives rather useful when it comes to solving apparently impossible crimes. Tonight, the delicate balance between his two realities is shattered when his son Rex is kidnapped by an escaped convict, a man Britten arrested ten years ago.

Although he may well forever be the Janitor in Scrubs, Neil Flynn is pretty believable as put-upon Everyguy Mike Heck in this gentle family comedy, perfectly matched by Patricia Heaton (forever Mrs Raymond in Everybody Loves Raymond) as wife Frankie. At times it plays like a soft Malcolm in the Middle, but the three kids - dim jock Axl, klutzy enthusiast Sue and the plain bizarre Brick - give it life. Tonight, the kids are increasingly bothered by Frankie's all-seeing eyes in the back of her head, while a reluctant Mike is forced to attend Parent Day at Brick's school. Class comedy continues at 8.00pm with Modern Family. Alex is counting on the clan working together for her school art project but, surprise surprise, they're too busy arguing with one another.

Ahead of co-hosting the European Championships in June, the government of Ukraine has been projecting a modern image of luxury shops and a thriving culture, as well as investing billions in bringing the infrastructure up to scratch. All is not rosy though; apart from the disturbing treatment meted out to imprisoned former president, Yulia Tymoshenko, life since independence in 1991 has been hard for many of the country's young people. Channel 4's Unreported World team went to Ukraine to meet some of the thousands - UNICEF estimates as many as 100,000 - living a dangerous subterranean existence in pitch-black basements and passageways under the streets of Kiev. They are a lost generation of teenagers, who have run away from broken families, alcoholism and abuse; now an embarrassment to Ukraine's government, many inject drugs or sell sex, risking syphilis, hepatitis and HIV/Aids.
