Karan is a cartoonist, and he uses his animated creations Hum and Tum to share his own particular observations concerning the battle of the sexes. Rhea is a confident and forthright young woman, and over the course of ten years the two drift from indifference to respect, friendship and eventually courtship. Hum Tum is a light hearted (and very western) musical, romantic comedy from the infinite Bollywood stable.
