Finals week means final battle for the 3 O'Clock Club! Zel, Drew, Wash, and Q are ready to take on whatever the portal spits out, whether it's Promzillas or the Specter of Graduation. Meanwhile, Arch and June are taking it to the source--they've gone INSIDE THE PORTAL to face whatever, or WHOever, is generating all this madness. Will the Clubbers be able to shut down the portal and stem the tide of weird that's enveloping their school? And even if they find a way, will Arch have the guts to pull the plug?
