Please help me identify the movie where;

# A dad is dumb

# his shepherd son is killed by arrow.

# Archer is boss of a mine

# dumb dad avenges his son's death.

There's a movie clip in you tube, it is listed as "The Blind Rich Man Fell in Love with his Nurse". I found out that the movie title is Maid No. 12. The clips are good and you can figure out the movie by watching it, however, I don't want to see the clips of main points, I want to see the movie.  I want to feel the relationship grow--does that make sense?  Now my problem is---where can I find this movie.
