When a nerd and a bad boy get together, it's pure chemistry.
Scientist Maddie Clarke likes to keep her life organized and on schedule. But when bad boy Sam Hennessy returns home fifteen years after calling her a nerd, her life is thrown into chaos.
Desperately needing a subject to test her latest pheromone-based perfume on, she chooses Sam. After all, he's perfect. There's no way someone like him would fall for a dork like her without drugs and/or alcohol being involved. The only thing is, Sam isn't the sort of guy who likes to be manipulated, even by someone he finds suddenly and unexpectedly sexy.
