Maya is kidnapped and implanted with the late spy Nightingale’s memory chip. The sinister Dr. Aris threatens to cut off her little sister’s life support unless Maya tricks four criminal mafia leaders into proposing and handing over fragmented secret codes. Maya navigates dangerous cat-and-mouse games with each gang boss, gradually uncovers Aris’s fabricated bomb conspiracy. Teaming up with the four dons, she exposes the foundation’s crimes, rescues her sister, dismantles the criminal organization, and builds a peaceful ordinary life far from all danger.
