Plot synopsis: The untold story of nothing less than the birth of rock ‘n’ roll. Guided by Sam Phillips, young musicians like Johnny Cash, Elvis Presley, Carl Perkins and Jerry Lee Lewis combined the styles of hillbilly country with the 1950s R&B sound created by artists like Muddy Waters, B.B. King, Fats Domino and Ike Turner, and changed the course of music forever.
