Hear the entire Abba story with all four members of the band in interviews and special sequences filmed with them, rare archives, and a feast of Abba songs. It starts with their pre-Abba careers, then the inside story of how they conquered Eurovision (first in Swedish, then in English), and then how they've continued to conquer the world several times over. We see them in performance and even going into the sound studio to discover how the Abba sound was created.
