Hi everyone,

I've been trying to figure out the name of a bollywooBmovie that I've watched many many years ago. I have few memories of significant events in the storyline. Can anyone help me find the actual name of?

So the events are;

1. There's an evil stepmom/mom who gets caught to her husband while having an affair with another man. She immediately shoots her husband when she gets caught.

2. She and her partner then try to cover up the murder by placing the dead body in a Jeep and pushing it through an edge of a cliff to make it look like an accident.

3. However, the family driver witnessed the shooting , yet is kept silent through intimidation.

4. The main protagonist is this woman's son / stepson who's finding clues for his father's death suspecting foul play. At one instance, the mother and her partner plan a bomb on their sons Jeep to kill him. However , she misses aim and instead kills an evil twin in the process.

Appreciate if you'll could help me with finding the name of this movie! Thanks in advance!!
