Will Nancy and Jack be allowed to embrace the future, or will their histories forever bind them to the past? Drama teacher Nancy O'Brien puts her ambitions on hold to support her family, and returns to her idyllic seaside home town, St Nicholas Bay. Jack has his own reasons for heading to the Bay; a young widower desperate to come to terms with his loss, he hopes setting up home there with baby son, Toby, might just enable him to survive the future. As Nancy and Jack become closer, not everyone is thrilled, in particular Toby's grandmother, who can't bear to see her late daughter 'replaced'. When Fraser - the only man Nancy's ever really loved - reappears, her living arrangements with Jack seem set for disaster.
