After committing a murder for his lover, Gloria, the famous painter Jack is forced to go underground. In the harbor district, he saves the poor Malaysian girl Song in front of two intrusive sailors. She loves him for it, and together Song and Jack appear in the tingle dungeon of the port, he as a knife artist, she as a dancer.
