Siri Dahl has grounded her stepdaughter Kimmy Kimm, which means that Kimmy can't go out to do anything fun - even though her band is supposed to be taking part in a music competition tonight. Kimmy's bandmates, Penelope Kay and Gia DiBella, come over and tell Kimmy that they have a plan to get Kimmy out of the house. Siri then catches Kimmy talking to Penelope and Gia, and sends Kimmy back to her room.
Now that Penelope and Gia are alone with Siri, the two girls get started on their plan, flaunting their sexy bodies in an attempt to seduce Siri so she'll let Kimmy leave the house. The plan seems to be working, but backfires when Kimmy is caught spying on the seduction. This causes Siri to have second thoughts, but when Penelope and Gia suggest that Kimmy join them so they can have a FOURSOME instead of a threesome, Siri gives in to temptation!
