A suburban family's relative calm and predictable reality is shattered when their daughter freaks out on a bad trip out one night in her wardrobe. The resultant over-reaction actually seems more understandable when the girl admits that acid is the least of her worries.
There are several interesting details in this second adaptation of this script, not least the hairy Hells Angel Sandy Alexander exploiting Maxie in a perfect New York crumbling apartment block.
The real devil of the piece is, however, the straigh-laced nextdoor neighbour kid (dad Hal Holbrook) who has been supplying everyone. His justifications for dealing (despite being near strangled by Maxie's dad Eli Wallach) reaches Sackler levels of inhumanity.
The last act involves Maxie's committal, to what I presume is Bellvue, and the detail of the security arrangements and lack of privacy in the institution are far better observed and rendered than Michael Bacall and Jordan Melamed's, make-it up-as we-go-along approach, in Manic (2001).
