A teenager with a tendency to self-destruction returned home after being suspended from boarding school, only to find that his grandmother had moved in, but he had no idea that he had a grandmother. This grandmother who fell from the sky was not only drunk and energetic enough to drive him and his friends down, but also vulgar, funny, fearless, and even flirtatious, which is the best of grandmothers. This is followed by a funny but poignant friendship story that crosses the generation gap between grandparents and grandchildren.
