Staring at the stunning diamond solitaire on her finger, Kaitlin is finally getting the chance to introduce her best friend, Zoe, to her perfect fianč. She hasn't known Greg long, but he looks after her, and he loves playing dad to her young daughter. How could she say no when he's already planned their elopement? As guests arrive, why is Greg acting so shifty? And is that a flicker of recognition on Zoe's face? And why does she look terrified every time her phone rings? Kaitlin watches as Zoe knocks back her white wine and makes a beeline for Greg. After a heated conversation, Zoe stumbles toward the door and flees the party without looking back. Days later, the police knock at Kaitlin's door - Zoe is missing. Kaitlin wants to believe her loving fianč is not to blame, but she knows what she saw the night of the party. And when he lies to the police, can she trust the man she's marrying? Could Kaitlin and her precious daughter's life now be in danger too?
