This movie has a plot based on a man who spent his younger years as a DEBT COLLECTOR, so the basis of the movie contains strong violence, which is graphic in some parts but infrequent, as follows:
A man is beaten visciously and his head is stomped into cement (this is very visible and can be very disturbing)
A man has his throat slit (not overly gruesome but there is blood)
A lady is punched in the face.
2 Men Stab each other continuously (very graphic and close-up)
A lady is beaten off screen. We see a bloody aftermath.
A few fight scenes that are brutal and realistic. The entire film has a very realistic violent sense to it.
