Jerri's back out of prison and back to being a freshman at Flatpoint High. . . again. She's determined to be a proper girl, if only that little devil on her shoulder would stop trying to convince her otherwise. Coach Wolf encourages her female students to remain chaste and convinces Jerri that she can reclaim her virginity. All the girls take to wearing ""Never Been Touched"" ribbons with a cherry dangling from them.

Coach Wolf assigns marriages for her students for a class project. Jerri get paired up with Ronnie Leggett. After Jerri finds problems with her new “marriage,” she learns that it is not as easy as she thought it will be. Will Jerri be able to save her “marriage” and her grade?

After deflowering a male classmate, Jerri finds out that she has contracted a series of STDs (syphillis infested with crabs which are carrying gonorrhea) and must inform all her partners of her discovery. Meanwhile, Mr. Jellineck and Mr. Noblet have problems concealing their own bout with a particularly noticeable STD.
