The damsel in distress seeks the guy's help. Sorry, my mobike is out of order, he pleads. But one glance at the girl is enough to melt his heart. The two have a roll down a snow-covered mountainside. The girl is reunited with her group. Bus! Love blossoms before you can bat an eyelid.
But hang on, Deewaanapan, as the title suggests, is not really about love. It's about insanity.
