An episode of The Sopranos where Tony and the gang have to fight Kazuma Kiryu:

INT. TOJO CLAN HEADQUARTERS - NIGHT

Tony and the gang are gathered around the conference table, planning their next move.

Kazuma Kiryu walks into the room and addresses them.

Kazuma: Tony, I've come to settle things once and for all.

Tony: Kiryu, you're not welcome here. Get out before I have my guys break your legs.

Kazuma: I'm not afraid of you, Tony. I'm going to take you down, just like I took down the Yamaguchi-gumi.

Tony: Is that a challenge?

Kazuma: You bet it is.

The two men stare each other down, neither backing down.

Finally, Tony speaks up.

Tony: Alright, Kiryu. You're on.

The two men step out into the night, ready to fight.

As they battle, the rest of the gang members cheering them on, it quickly becomes clear that Kiryu is the better fighter.

Tony is knocked to the ground, and Kiryu stands over him, ready to deliver the finishing blow.

But before he can, he's stopped by a gunshot.

Kiryu looks to see Tony's wife, Carmela, standing there with a smoking gun.

Carmela: That's enough, Tony. It's over.

Kiryu nods, and walks away, leaving Tony and Carmela alone.

Tony looks up at Carmela, and it is clear that this is the end of his life of crime.
