In 1949, two young Cuban musicians, brothers Cesar and Nestor, leave Havana for New York. By day they work hard, by night they are the Mambo Kings: packing out clubs, dance halls and theatres with their sensuous, pulsing Latin music. This is the captivating story of charming, vivacious womanizer Cesar and quiet, romantic Nestor - still nursing an unrequited love for beautiful Maria of my soul - and their changing fortunes as they try to make it big in America.
