Cat's Eye, a trio of thieves, have once again robbed a statue right under the nose of police inspector Toshio. He drown his sorrows in a café named Cat's Eye, run by his girlfriend and her two sisters, unaware that at night they become Cat's Eye.

Cat's Eye plans are cut short when they found that their dad's painting was already stolen and the gallery owner killed. The girls now need to get the painting back and clear their name.

Cat's Eye's next target is The Lakeside House at the Ohashi Museum of Art. The museum's security is managed by the father of Kono, Ai's classmate and secret crush. Knowing the theft could cost Kono's father his job, Ai opposes the plan.

Asatani, a brilliant detective from headquarters, suspects an informant within Cat's Eye. She has her suspicions about Toshio's girlfriend, Hitomi. Although Cat's Eye's next heist seems simple, Hitomi is concerned about Asatani's wary eyes.

Kamiya, a jewel thief who goes by the alias Rat, becomes intrigued by Hitomi at Cat's Eye café. He learns the true identity of Cat's Eye after successfully stealing the painting they were targeting.
