The night before her wedding, ICU nurse Olivia discovers an Instagram post that shatters her world: her surgeon fiancé's distinctive surgical scar—one she knows intimately—visible on another woman's feed. When she confronts Callum, he confesses to a six-month affair with his medical school ex, who's now pregnant and has hijacked their entire wedding, down to the venue and the date. But as Olivia prepares to walk away from everything, a midnight call from Callum's mother reveals a devastating secret that connects their families in ways neither of them knew. What Olivia thought was a simple case of betrayal spirals into a twisted web of revenge, manipulation, and buried history that spans generations. Some scars run deeper than skin—and some secrets destroy more than just one wedding.
