Arabikatha??narrates the story of Cuba Mukundan (Sreenivasan) who can be called an ??mpractical idealist.??He is a staunch leftist who lives for the movement. Circumstances force him to take up a job in West Asia. But he finds himself a misfit in a highly materialistic world. He has always had a soft corner for China as a result of his leftist leanings and when he meets a Chinese girl, she quickly finds a special place in his heart.
The movie depicts mukundan who live in this present society where sticking to any ideology without any compromises is perceived as something of an anachronism. Mukundan often fails to change with the changing times
