Set in 1930s Beijing and Shanghai, the musical centers on Mu-hyeok, an orphaned cart driver whose only companion is his battered cargo bicycle. His life changes when he meets Deok-hyeong, a former pickpocket, and Ja-gyeong, an idealistic intellectual interested in the independence movement. Together they form a small “revolutionary group” and plot a daring raid on a Japanese bank, treating robbery as a righteous act to fund the anti-colonial struggle. As their scheme succeeds and their activities move to Shanghai, friendship, loyalty, and conflicting ideals begin to pull the three men in different directions. Against the backdrop of Japanese imperial expansion, the story explores what kind of “anarchist” one can be when the cost of freedom is sacrifice, and whether the utopia they seek can exist beyond their own hearts.
