In A huge table tennis room that acts as a makeshift dance hall at Kohinoor Club in Kurla, six Japanese women take their positions, facing a wall-to-wall mirror. As soon as Katrina Kaif's superhit number, Sheila Ki Jawani, starts blaring on the speakers, they begin their dance practice under the watchful eye of instructor Satish Vaidya aka Sam. Though dancing to the lyrics of an unfamiliar language, their movements - the hip twirls, hand-leg coordination and gestures that convey the sensuous lyrics - are perfectly in sync with the beats. They smile through the practice and even lip-sync to the English parts of the song.
