Chen, a young kid, is battling a cultural conflict between his Russian born mother and Israeli father. She is cultured and used to the finer things in life, including theater and fine dining. He is gruff on the outside but sweet on the inside - a Sabra; and looking to make his young son a man rather than the wimp his mother is raising. One day, Chen stumbles upon a ballroom dance class for young people and sees Natalie, a stunning Russian young girl he falls in love with immediately.

The teachers are a pair of former Russian world champions who never quite fulfilled their potential, but find themselves battling their demons through the instructions of the kids.
