Padman's hitting all the right notes already.

The film's latest song 'Hu Ba Hu' reveals a strong relationship between Akshay Kumar and Sonam Kapoor as they embark on a journey to educate women about menstrual hygiene.

In a nutshell, the three-minute song depicts Akshay's efforts from the beginning, when he starts working towards his goal of understanding menstruation and also finding a reasonable solution for it, till the end when he flies to New York having successfully achieved his objective.

Slated for release next year on January 26, India's Republic Day, Padman is based on the true story of Arunachalam Muruganantham, the man who built machines to enable women in rural areas to manufacture low-cost sanitary pads for their communities.
