《母娘監禁》

A young teenager, Chizuru makes a suicide pact with 2 other school girls. However, only one of Chizuru"s friends actually goes through with it and dies. Chizuru runs from home to Tokyo and finds Minoru, whom she believes to be Mr. Right. However, Minoru is actually a thug who apparently has nothing to do but rape girls and then share them with his two buddies in crime. Chizuru finds this out the hard way and is coerced into luring her other friend (who did not die from the suicide pact) out so that Minoru and his gang can rape her. Chizuru"s mother finds out where she is living in Tokyo and comes to try and pick her up. Of course, not even her mother is out of bounds for Minoru and co.
