After surviving a tragedy, paramedic Jenny struggles with PTSD and her life spirals out of control when she falls into a gambling addiction. Concealing her suffering from husband Chris, best friend Alison and daughter Rosie, Jenny returns to work, but she is unable to deal with her crippling anxiety. During a public meltdown, a stranger comes to Jenny's aid, Sasha, and the pair strike up a bond. Later, Jenny makes a confession to Sasha about the extent of her gambling addiction.

Jenny is confronted by a heartbroken Chris, who has discovered another secret she has been hiding. Finding sanctuary at Sasha's, Jenny feels her resolve weakening as the lure of the poker tables, and a shiny new bank card, becomes almost too hard to resist.
