Recently divorced Nikki is a single mom looking for a fresh start in a new town. After she befriends fellow single mom Liz, the vivacious Liz takes Nikki under her wing, even giving Nikki a job at her popular boutique. To Nikki, Liz represents everything she aims to be, and she takes Liz's advice on her career, child-rearing, and love life very seriously. She even ends a new relationship with Gavin, a charming neighbor, when Liz points out red flags Nikki didn't even know to look for. But after Liz goes missing and all signs point to Liz's jealous ex, who she was in a custody battle with, Nikki is beside herself with grief. To her surprise, Gavin becomes her rock and even helps her dig into Liz's suspicious ex to help her (and the cops) close the case. But after Liz's ex is arrested for her murder, Nikki spots new clues no one else sees that point to the true killer.
