Comedy starring Cameron Diaz and Justin Timberlake. After being dumped by her sugar daddy, tough-talking bad girl Elizabeth Halsey (Diaz) reluctantly returns to her former job as a middle school teacher. Back in the staff room she has soon set her sights on a hot new substitute teacher (Timberlake), who also just happens to be heir to a large watch fortune. Unfortunately, there is just one small obstacle standing in Elizabeth's way: his butter-wouldn't-melt girlfriend, Amy (Lucy Punch).
