This Thornhill Diaries edition (confusing listed as both #19 and #20, but actual Volume 19 is "Twisted Passions 4") has a lousy cast and uninteresting stories, only tangentially related to its title premise of the Thornhill girls softball team.
The script name-drops Tori Black and Ariel X but neither afctress appears on screen. Instead, the cast includes some obscure starlets like Jodi Starr and Misty Anderson, who give unimpressive performances.
Darryl Hanah appears as the coach and there is the usual older/younger lesbian action. The overused gimmick of a high school girl forced to have sex as part of the Thornhill U. entrance application interview is trotted out again here.
It's easy to see why the "Field of Schemes" series was discontinued by Girlfriends Films long ago.
