At school Bethan is full of herself as she tries to make a good impression on new girl Cam who she has a crush on. However, Bethan's home life is far from perfect as she becomes ever more combative with her abusive father, Dilwyn.

Bethan is taken aback when her mother suddenly announces that she's planning to leave Dilwyn and is concerned about the danger Trina will be in when her dad finds out about the affair. Meanwhile Bethan's relationship with Cam reaches a new level.
