Poison Ivy – The New Seduction
As a young child, Violet (Jaime Pressly of My Name is Earl), her sister Ivy (the only – tenuous – relation to “Ivy” in “Poison Ivy”) and her mother are thrown out of the house when her mother is found to be having an affair with what appears to be the gardener.
This is a problem not because her mother is married to the man of the house, as you might expect (and as might be normal), but because she is also having an affair with the man of the house, and this comes to light in loud fashion when the woman of the house walks in. Thus, they are kicked out, and have to find a new place to live.
