Terri Venessi (Mary Kate Schellhardt), a local straight-A student and ‘deli girl’, always seems to be at odds with the cheerleading captain, Karen Ridgeway (Hillary Tuck). Terri is the daughter of Grace (Valerie Harper) who is a widow and Karen is the daughter of Millie (Shelley Fabares) who have been known rivals since the day their friendship was strained. One day, their pranks on each other go too far when a revenge-fueled stink bomb in Karen’s locker gets out of hand and the school has to be evacuated for two days as a result.
