Zombie Hood (2013) on Netflix

Plot summary

The outbreak starts when a virus moves through a nightclub and then through the whole city. Across the country comes a night of unrest, and the authorities lose their grip as hospitals fill past capacity and the dead return to attack the living. People abandon the built-up areas for the countryside and its villages. On the edge of Nottingham a small band thrown together puts its hopes in Sherwood Forest. Supplies are scarce, and the group quarrels over what to do, with Sam, a wayward teenager whose personality is confused and dangerous, second-guessing Dermott, the police officer trying to lead them. Rik, a caring young man, cannot accept what has become of mankind. The group's best hope lies in reaching an army or refugee camp, though a small child and an old man slow them down.
