Adultery tears apart a long-standing friendship. Based on the opera La Cavalleria Rusticana.

A bright, pretty and determined young lady named Anna Lee quits the police department in search of adventure, and joins a small and somewhat stuffy detective agency, whose members don't look particularly kindly on her short skirts, somewhat cavalier attitude toward agency rules--like showing up for work on time--and her overall demeanor. However, the agency's owner takes a shine to her and assigns her to what seems to be a relatively straightforward case: finding a young girl who's gone missing and whose family is worried about her. As it turns out, the case involves quite a bit more than just a missing girl.

3 young children living in commission flats in Melbourne are left to try and fend for themselves, after their alcoholic Dad leaves them.
