SAMBO AND BJJ ... THE KNOWLEDGE MERGER CONTINUES.

This has buddy revenge movie written all over it.  Picture this: 

They killed his stepson [can be any family member, really].  Now, armed only with his Jiu Jitsu kimono and his trusty Romanian companion - an expert in Russian Sambo, he'll exact his own brand of bone-breakingly painful revenge on them all. 

It's just needs a sick title to bring it all together.

These bros of ours at Phuket Top Team - they are are unstoppable with the amazing content.  Watch Silviu Vulc and Silvio Braga, resident Sambo and BJJ experts, respectively, sharing their knowledge on leg locks.  Thanks PTT.
