Popular actress Ryoko Shinohara returns to the airwaves in the new series "Ogon no Buta" (The Golden Pig; Nihon TV, Wed., 10 p.m.), in which she plays an unconventional investigator for the National Tax Agency.

In last week's premiere, Shinko (Shinohara) was introduced as a young woman who resorts to petty swindles in order to get by. One day she tries her luck with a man on the street who is not fooled. However, instead of calling the police he offers her a job. He works for the National Tax Agency and thinks she might make a good investigator.

In this week's episode, the investigating team is looking into reports of a police slush fund. Shinko's aggressive colleague, Suguru (Masaki Okada), discovers that the handwriting on most of the expense receipts is the same. The evidence seems irrefutable, but Shinko is reluctant to get involved since she's already had dealings with this particular police station.
