Pleng is a charming and beautiful English tutor. Her ordinary life takes an unexpected turn when she is asked an extraordinary favor; to help one of her students dump her Thai boyfriend named Gym. Unfortunately, Gym doesn't understand English so Pleng's student records her voice message and asks Pleng to translate her message to him.
When Gym realizes that he is being dumped, he pins blame on Pleng for his girlfriend leaving him, being that Pleng taught his girlfriend the English to pass her US job interview. It is at that moment Gym persuades Pleng to teach him English too, hoping to go to the US to reconcile with his girlfriend. Pleng has reservations, but agrees.
At the same time, Pleng has fallen in love with another one of her students, Pruek, a handsome guy from a good family.
