Tre, a slacker, uses his brains, not his brawn, to seduce a woman seeking revenge against her husband. The woman, a brassy but vulnerable actress/waitress named Nina, moved out of the house after discovering that her husband had kissed another woman for 10 seconds. Nina's more stable and responsible friend Kakela plays host and witness to their illicit affair. Seeing Nina fall from grace, Kakela begins to question her own devotion to her fiancé, Gabe. It is Tre who proposes the perfect experiment to test Kakela's love for Gabe. The experiment only lasts for 10 seconds, but it sparks a chain reaction that would change their lives forever.
