Again disney has wrapped its magical fairy hands around this tale making it two movies, when in reality this tale is quite short.
There is a young girl, who is working out in the fields. Her sandalia falls off and a eagle (or hawk) then picks up the shoe. She chases after it leaving her family just for the shoe, which the bird drops on the kings lap. The king orders her beheaded but sees her beauty and declares her his wife, also ending in forced child birth of several sons.
(Have yet to find how she dies.)
