Two sisters who couldn't be more different are unaware of their father's double life with two families and the existence of the other until his sudden death. While stuffy Sandra has no need for such a relationship, chaotic Sandy never leaves her new-found sister's side.
Unfortunately the movie Plötzlich Schwester is not yet available on Disney Plus.
