A bankrupt single mother makes a horrific discovery: her younger brother and sister-in-law cannot conceive a child of their own. Terrified of losing out on a massive billion-dollar inheritance fund, the couple secretly kidnapped her infant son. They locked the little boy in the basement and subjected him to cruel abuse.
Desperate to rescue her child and get revenge on the treacherous pair, she strikes a marriage contract with the coldest, most ruthless billionaire in the city — who happens to be her son’s biological father. United by the agreement, she launches a fierce counterattack to take back her baby and punish the heartless relatives.
