Darth Vader is Luke's father!

Memo's mother is killed at the very beginning, he is then captured by a dentist that puts him in his office tank. His father befriends a retard named dory and goes to find Nemo. Nemo escapes the tank by playing dead and going down a sink drain. His father thinks he's dead when he sees him and starts to go home. Dory gets caught in a grouper net, and Nemo (now free) gets the grouper to all swim in the same direction to get free. The end.

Sounds great. Except Dory isn't retarded she had short term memory loss.

Now say a movie you haven't seen and I'll ruin it for you

I wouldn't care.
