Build a movie plot around this: Who is Ginny's younger sister? Sam
A:
Awkward high school sophomore Samantha "Sam" Baker (Molly Ringwald) struggles to get through the day of her 16th birthday, which her entire family forgets because her older sister, Ginny (Blanche Baker), is getting married the next day. Sam is also plagued by her ongoing infatuation with popular and attractive senior Jake Ryan (Michael Schoeffling). Her day at school fares no better when she finds out that her completed "sex quiz," which she surreptitiously slipped to her friend, never reached her (and, unbeknownst to either of them, was intercepted by Jake Ryan himself). Sam panics, as the quiz contains personal information, including the fact that she is a virgin and is saving herself for Jake. At the same time, she doesn't know that Jake has the hots for her as well, but is too insecure to even talk to her.Samantha has a whole new set of problems when she arrives home to find that both sets of grandparents are staying for the duration of the wedding visit.

Sam's grandparents force her to take him along to her school dance that night and, to Sam's amazement, it takes "The Donger" only five minutes to find an unlikely girlfriend: the tallish, large-breasted jock, Marlene, promptly nicknamed "Lumberjack."A running subplot involves a geeky freshman, (Anthony Michael Hall) who continually (and unsuccessfully) tries to bed his love interest, Sam, to satisfy a bet with his friends. The character is referred to on several occasions in the movie as either "Ted" or "Farmer Ted", but he is credited solely as "the Geek."In the auto-shop room during the dance, Sam and Ted begin talking, and Sam confesses her love for Jake. Upon hearing this, Ted tells her that Jake has been asking about her at the dance, and they agree that Sam should just go and talk to him. As she's leaving, Ted reveals the wager to Sam, who, in her excited state, agrees to loan him her panties to help him win a dozen floppy...
