Attack of the 50 Foot Cheerleader

Cassie Stratford is a plain science nerd, whose mother was captain of the cheersquad at Iron Coast University and president of Zeta Mu Sorority, so she is pressured to join both cheerleading and the sorority. However, Brittany Andrews, Zeta President and Cheer Captain (who has a Napoleon complex), rejects her.

Cassie works in the Biology Building of the University, where she and her friend Kyle are working on a drug that turns things beautiful. In the night, Cassie steals the drug and injects herself with it. While she does become beautiful and makes the cheer squad when one of the cheerleaders is injured, she then discovers the drug has a side effect when she starts to grow taller and taller until she is a 50-foot tall giantess.
