The Men's Room - Episode Guide

At a London university, a turbulent love affair starts between bored mother of four Charity and her womanising professor Mark.

Mark finds deceit easy but Charity, new to adultery, is more nervous. Her friend Sally reassures her the sex will be great.

Charity's husband finds out about her and Mark, and starts an affair of his own. Mark continues a life of deceit, but his comfortable existence is under threat.

Mark has not seen Charity in two years, during which time his wife Jane has thrown him out and his daughters have grown up.

Mark and Charity have been living together for four years, and Mark is ready for marriage. He worries that without the commitment, he will stray again.
