Antaheen is based on a story of the director Aniruddha Roy Choudhury. It shows urban life in a metro like Kolkata where relationships develop online, love and bonding exist even though couples live separately, and where longing, greed, journalistic scoop, parties and tragedies coalesce into an integrated whole. The film has a lyrical quality about it, and veterans like Aparna Sen and Sharmila Tagore are at their ravishing best.
In the film Aparna and Kalyan Ray play a couple who live separately. Aparna is an editor in a publishing house, while Kalyan is immersed in his own cushy life in Mumbai devouring books and downing fine wine. Radhika Apte plays a TV journalist on the lookout for sensational stories. She meets the cop (Rahul Bose) in a party and a relationship develops between them. There is an online angle to their relationship as well. The character of the cop (Rahul Bose) appears a bit too poetic for a cop.
The title of the film can be attributed to the 'endless wait' of some of the principal characters for their desires and longings to come to fruition. Like the character of Pishima (Sharmila Tagore) of the cop who waits for the unknown phone caller with whom she started a conversational relationship with an inkling of it having the potential of becoming a full blown one. Even the relationship of Aparna and Kalyan, quite affectionate at times, doesn't head towards reconciliation. As Rahul Bose's character says in the film "Possibly his brother Kalyan & sister-in-law Aparna aren't too sure of what they want from the relationship." Moreover, towards the end with the tragedy that transpired, would Rahul now wait endlessly for a reunion in after-life with his paramour?
The supporting cast includes Mita Vashisht, Arindam Sil and others.
