Ari is just a regular avatar from Blockville who loves hanging out with his two best friends - Zeke, an obby and parkour pro, and Jez, the ultimate hacker and Queen of Tech. Ari and his friends are off on a school excursion to a volcano! But they are disappointed to hear it isn't an active volcano. Boring! And to make matters worse, they are forced to take the school nerd, Gabe, into their group with all his totally annoying habits. But when the volcano suddenly turns out to be a bit more active than expected, can Ari and his friends escape the lava in time?
