A new case baffles both the police and Cat's Eye when several paintings which were just stolen by Cat's Eye are mysteriously taken from their secret hiding place and returned to their owners for a reward. To their immense surprise, Hitomi and Rui find out that Ai is behind this, though not on her own volition; she has been hypnotized by an attention-seeking spendthrift, who has deduced that she is part of Cat's Eye and now uses her to finance his extravagant lifestyle. But with his debt holders finally calling in, the villain eventually drives Ai into attempting to kill her own sisters!
