Sam is a movie producer. He is 48years old and still single. Never married, but suddenly decides he wants a family. However, even with his hope, he has no idea how to build relationships as he lived single and free his whole life. The story finally deepens as he meets a Lisa, who is a widow and much younger than him. Considering the age gaps, the story illustrates the two characters' mental age as a serious, but interesting love-comedy.
