Title: Queen Sized Movie plot: Maggie Baker (Blonsky) is an overweight 17-year-old girl who suffers being taunted and ridiculed at school and badgered to lose weight by her overbearing mother (Annie Potts) who is worried she will get diabetes like her late father. Maggie and her mother are estranged and do not get along. The movie starts by showing what Maggie goes through every day at school.

Liz overhears and decides to nominate Maggie as a joke. They would take her off the ballot so her friend Tara will take the crown since she is a shoo in to win. The joke is on her though as many students who are sick of the popular kids get excited about Maggie being the queen,...
