After writing a hit song, Will Freeman was granted a life of free time, free love, and freedom from financial woes. Now he's single, unemployed, and loving it. So when Marcus (the oddly charming 11-year-old next door neighbor) stops by, Will's not so sure about being a kid's new best friend...until Will discovers that women find single dads hot. Well, that changes everything. A deal is struck: Marcus will pretend to be Will's son, and in return Marcus is allowed to chill at Will's house, playing ping-pong and gorging on steaks - something Marcus's single, needy (and very vegan) mother would never allow. Before he realizes it, Will starts to enjoy Marcus's visits, and even finds himself looking out for the kid. Could it be that maybe there's something to be said for being a (sort of) responsible adult - at least in a young boy's eyes?
