Trailer for Green Street Hooligans: Underground.
Fourteen years ago, Danny turned his back on football violence and channelled his ability to fight into the world of MMA. But when Joey (Billy Cook), Danny's younger brother, is killed in an organised fight, Danny knows the only way to find out who killed him and avenge his brother's death is to return to his old manor and get back into the firm. But Hooliganism has moved on and Danny's fighting skills will be put to the ultimate test.
