Facing an immediate hundred-thousand-dollar hospital bill to save her grandfather's life, Tess assists Knox Romano, a dangerous mafia heir poisoned with an intoxicating chemical in a dark alley. Following a night of feverish intimacy, she takes only the exact medical fee and vanishes before dawn. Two months later, an ultrasound reveals an astonishing complication: she is carrying Knox's triplet heirs.
Knox tracks her down across the boroughs, offering an eight-hundred-million-dollar contractual marriage allowing her complete financial freedom once the children are born. Expecting cold syndicate formality, Tess is stunned when the fearsome mob patriarch and his entire clan shower her with unconditional adoration. As Knox's possessive jealousy flares whenever rival suitors approach, their temporary bargain becomes an unbreakable bond.
