With Lacey behaving strangely following her 16th birthday party, Ash soon realises that something is amiss - before correctly guessing that the teen must have caught Martha (Carli Norris) drinking yesterday.
Heading straight home, a furious Ash (Holly Weston) confronts her alcoholic mum, branding her thoughtless and selfish for not staying on the wagon.
Although Martha is initially apologetic, she soon gets fed up with Ash's lecture and fires back with some harsh words of her own. Can the fractured family recover from this?
