Meet Cassidy Levi. She was the nerdy, straight A student going into sophomore year. Over the summer, Cassidy changed from nerdy to average, but still has straight A's. Meet Spencer Conrad. He's the cliché popular jock. He's got the hot, bitchy, cheerleader captain girlfriend that every guy in the school wants. When Spencer starts failing Chemistry, his dream of becoming a pro baseball player flies out the window. Cassidy is forced to tutor him since she is the smartest one in his class. Will teaching Spencer Chemistry lead to chemistry between the two, or will it all blow up in their faces?
