Pregnant Olivia was forced to induce labor and donate bone marrow for her twin sister Chloe, who faked leukemia. Biased parents and husband Lucas, misled by Chloe's lies, treated her cruelly. Devastated, Olivia was hit by a truck, losing her baby and ability to conceive. Chloe faked a suicide by drowning and framed Olivia. Enraged Lucas locked claustrophobic Olivia in a coffin and dumped it at sea, where she suffocated. Her spirit was bound to Lucas, forced to watch the unharmed Chloe cuddle and kiss him in a wedding dress. Later, the coffin washed ashore with her body. Her best friend Daisy and loyal Alex uncovered Chloe's vicious scheme—she had long recovered from illness. Overwhelmed by remorse, Lucas killed everyone who harmed Olivia, then ripped out his fingernails and burned himself to atone. Freed at last, Olivia's soul drifted toward light.
