Scott Pilgrim's life is enviable and wonderful. The 23-year-old lives in Toronto and works as a bassist in a rock band called Sex Bob-omb. Recently, Scott is a little proud because he just met his dream goddess - a cute girl in high school, Lamona Follaus. The two of them are now in a sweet dating stage, and everything seems so good. However, this kind of life did not last long. Lamona's seven former friends soon found Scott, and Kurt also understood that he needed to fight these seven devil-like guys one by one, otherwise not only his love with Lamona would be in danger, but even his life would be in danger. As Scott and Lamona's relationship gets better and better, Scott and Lamona's seven former friends have an encounter, including a skateboarding expert, a vegetarian rock star, and identical twins. In order to stay with Lamona for a long time, Scott must eliminate them before they eliminate him.
