Forget the past
In the two years since Gemma’s husband Simon deserted their marriage to be with his lover Kate, Gemma has been raising their teenage son Tom alone. She’s finally making strides in moving on with her life until Simon and Kate’s sudden return to town throws her world into disarray again.
Re-establishing his bond with Tom, Simon asks him to attend a wedding reception he and Kate are having to celebrate their recent marriage, prompting Gemma to crash the soiree with her new boyfriend James (who’s also Tom’s teacher) on her arm. However, she gets drunk and blatantly accuses Simon of still wanting her.
Incensed, he denies it and urges Gemma to forget about the past, even persuading Tom to live with him and Kate. Unfortunately for Simon, the move to separate his ex-wife from their son only sparks Gemma’s new campaign to wreak revenge on him for what she sees as him destroying her life.
