Will Freeman lives a charmed existence as the ultimate man-child. After writing a hit song, he was granted a life of free time, free love and freedom from financial woes. He's single, unemployed and loving it. So imagine his surprise when Fiona, a needy single mom and her oddly charming 11-year-old son, Marcus, move in next door and disrupt his perfect world. When Marcus begins dropping by his home unannounced, Will's not so sure about being a kid's new best friend, until, of course, Will discovers that women find single dads irresistible.
