I think "Horse Power" movie was a remake. The original one was Telugu or Kannada or Tamil. I still remember the original one was dubbed in Hindi and was uploaded in masaladesi long time ago. If anyone get any idea or any information of that original film, please let me know.
The plot is that a housewife gets attracted to a horse trainer in here nearest garden, then she slowly develops a relationship with him. Later she kills him and gets arrested.
