Different
A young woman was left mentally disabled after a car crash twenty years previously, a condition which her mother has never come to accept. Thus she favors her other "normal" daughter and basically tolerates the other daughter's existence. It also doesn't help that her husband also has some mental disabilities. As the family slowly divides, the older daughter's unconditional love rises.
