If any parent or guardian has a child around this age, especially one who shows signs of trouble.
I highy recomend this film.
It was concieved, and co-writen, by a very young, Niki Reed. Who also stars as the troubled Evie Zamora.
The film centers around 'Tracey', played by Evan Rachel Wood (other film includes 'The Missing' as the kidnaped daughter), and how she falls, willingly, under the wrong influence of Evie.
Holly Hunter is superb as the Mom.
And Jeremy Sisto is very good as the 'half-way house junkie boyfriend' of the mom.
