Lexi and Brielle are sisters. Lexi is sixteen and twins with Greyson her brother. And Brielle is fifteen. They all arrive home right before school starts, only to find out that their mother's new husband is taking her to Japan for business. They are building corporations there and will be gone for two years at the least. But what surprises them more are the people who are staying to watch over them. Their new father's three sons. Instead of being sent to boarding schools they will be attending the high school in their home town, and all three of their new brothers are professors there. Living with three new men in their house is going to be tough, and their mother has left the three men with permission to raise and discipline them. The three men say they can handle it, and Lexi, Greyson and Brielle are going to give them a run for their money. But they are not expecting the way that these men will deal with them.
