All schoolgirl Mary Katherine Gallagher (Shannon) wants in life is a kiss. Not just any kiss, mind you - a big-time, hold-your-breath-'til-you-think-you're-gonna faint, Hollywood-style kiss. But no matter how hard she tries, no one will kiss her. Mary Katherine decides that the only way she's ever going to get what she wants is to become just like the people she sees getting those kisses in the movies.
