When Max, a restaurant musician, moves to the next door apartment, Baby has a crush on him and sees a chance to have a life again. Soon they start having a love affair, and Baby decides to quit smoking. However, her abstinence will be tough to deal with, when she notices Max still misses his ex-wife.
