Lillian's life is not at all like a roller coaster, but it's not going downhill either. The girl was once a promising student at a prestigious school, but a scandal broke out and she was expelled. Since then, nothing interesting has happened: vegetating in a provincial town, working in a supermarket, an indifferent mother, random guys and no hope for a bright future. But one fine day, an old friend asks Lillian to work as a governess for her husband’s children from his first marriage. And everything would be fine, but there is one problem: these kids ignite when they experience strong excitement.
