The Zee Brothers - Grivante

Who would you call during a zombie outbreak?
'BR'
The Zee Brothers return for their second adventure!
'BR'
This time answering the call from a local charter school that fears they may have an outbreak amongst their students.
'BR'
The brothers find themselves trapped inside the school, with no weapons, scared children and a host of hungry and toxic undead.
'BR'
They improvise with the help of the school lunch lady and a rather intelligent young student to try and stop the toxic infection from getting out of hand. 
'BR'
The aftermath leads Jonah, Judas and JJ to a small farm on the outside of town, where they find the cause of the outbreak with mysterious links to the brother's past.
