Special: Episode of East Blue
It is an abridged retelling. As the Straw Hat Pirates prepare to leave East Blue and enter the Grand Line, each of them reminisce about their journey to that point as they reaffirm their dreams.
I susggest to give the manga or anime a try.
The anime arcs covered should be about 12 hours of watch if you exclude the intro and outro. But if you don't have that much time then maybe you can check the specials (1.46 hours each).
