Several of the older boys, led by Frank Reilley and Stanley Runk, plot a revolutionary takeover of the camp.
Stanley Runk, armed with a large hunting knife takes Mr. Warren hostage while the other boys round up the rest of the staff and throw them into the camp's "jail".
The boys proceed to Low Pines, the sister camp for girls nearby, and capture the adults there as well.
A "Supreme Revolutionary Committee", or SRC, consisting of Frank Reilley and some of his more trusted cohorts, makes all important decisions.
Mr. Warren's gun is thrown into the cell and Egriss, fearing for his life, shoots Mason in self-defense, killing him.
Meanwhile, the girls at Low Pines have been calling for John Mason's blood due to his having raped one of the campers.
