Apple Tree Yard - Season 1 Episode 1

Genetecist Yvonne Carmichael is approached by a stranger who is impressed by her speech to a Commons select committee and with whom she finds herself having anonymous sex in a broom cupboard – a fact she obviously keeps from husband Gary. Nonetheless she is excited by experience and, suspecting Gary of having sex with his research assistant Rosa, continues the purely carnal affair, largely in public places where they could risk detection, such as Apple Tree Yard with its CCTV. However colleague George Selway finds out and lets Yvonne know in a very brutal way.
