Sneha, a beautiful young woman, was too rigid to fall in love. When he gave a knock at the locked doors of her heart that were meant to keep any man from entering her life, she resisted in opening it.
Love entered her life when she fell for Vikrant. However, life took a different turn and they parted ways. After being married to different people for a long term, they realise they are still in love with each other. There is no infidelity or cheating here, but only love.
Hangover attempts to redefine love, and in the process, make you realise that love has no definition, that it is boundless.
