It all started with a pack of cigarettes for Harry. He walked straight out of a convenience store without paying for the pack, and he would've gotten away with it too if it weren't for that silver Audi A4 in his blind spot. Renleigh Sterling couldn't believe the luck she was having. First, her mother decides to surprise her with a visit, expecting to meet the boyfriend Renleigh has been lying about for the past two years. Next, her car gets totaled in a local parking lot. When she gets out of her car to confront the other driver, instead of exchanging insurance information, she gets a brilliant idea. Renleigh offers to replace Harry's car free of charge and pay him a sizable amount of money on one condition: Harry has to become her boyfriend for the next three weeks while her mother is in town. Thinking that the job is harmless, Harry easily accepts, but a lot can go wrong in three weeks time. The first being that Renleigh forgot to mention that he has to give up smoking for this entire time period.
