The Last Anniversary

On the night of their fifth wedding anniversary, their neighbor Lily deliberately sabotages the water pipes as a ploy to seduce Mark, the husband. Serena catches them in the act, yet Mark shows no remorse whatsoever. Instead, he shifts all blame onto her and drives her out of their home. Serena returns to her wealthy family’s estate, determined to exact revenge. Using her access privileges, she locks and wipes all core data of Mark’s company and takes away the backup hard drives, pushing his business to the verge of bankruptcy. Later, she summons Mark to the Ward Manor, her family’s property, for negotiations. It is only then that Mark realizes his wife’s background is far more formidable than he imagined, and a full-scale counterattack is set in motion.
