Boogie (2009) on Netflix

Plot summary

In a bar, Boogie meets Marcia, the girlfriend of Sonny Calabria, a mafia boss. She asks whether he finds her attractive, and he tells her rudely that she is fat and walks out. A trial awaits Calabria, and a witness whose identity is unknown could testify against him. Calabria's people sound Boogie, a violent hit man who keeps his own rules, out about killing that witness, but his fee is more than they will pay, so they hire Blackburn, a rival in the trade. Angered, Boogie decides to grab the witness himself and hold the person until Calabria hands over the money he asked for.
