A socially-challenged otaku (Japanese slang for "geek") saves an attractive female from the unwanted advances of a lecherous salaryman while commuting on the local train route, only to become infatuated with the kind and thankful woman in a romantic comedy that takes its cue from a real-life romantic encounter. Densha Otoko (Takayuki Yamada) may not have much experience with the ladies, but what he lacks in romantic know-how he more than makes up for in gentlemanly instinct. When Densha notices an unruly drunk making a female train passenger (Miki Nakatani) uncomfortable, his snap decision to come to her rescue finds the relieved woman requesting his address so that she may send him a gift for his thoughtful display of kindness. Densha isn't the smoothest operator in town though, and in order to make a good impression he soon begins seeking out the romantic advice of his equally inexperienced internet friends. Now, as Densha strives to improve his social skills in order to win the heart of the woman he has grown to love, his romantic journey will find him realizing that there is much more to life than the heady philosophy behind the Matrix Trilogy.
