Plot

Kaido is a professional pickpocket who works the Tokyo subway with his young foster-daughter, Rei: She lets herself be groped while Kaido relieves the groper of his wallet. More often than not they're observed by a middle-aged cop, who generally lets Kaido go free. Rei is unsettled when Kaido takes on a young street punk, Kazuki, as an apprentice -- with instructions to make Kaido stop drinking. Kazuki, however, would like to go into business with Rei.
