A chance meeting with a stranger seems to provide a lifeline for a stressed-out mother, but relief soon turns to suspicion in this tense psychological drama. Ellie (Julie Graham - William And Mary) is unprepared for how different her life has become after the birth of twins. From being a successful business partner with husband Joe (Neil Pearson - Bridget Jones's Diary), she's now juggling working from home with the demands of the babies and her teenage son. She's grateful when the widowed Fiona (Hermione Norris - Cold Feet) offers to help out. Then Fiona starts taking over Ellie's life, and no-one else seems to notice.
