Portico Reeves is the greatest superhero you have never heard of. As Stuntboy, he has all the best moves and makes all the greatest saves, keeping everyone around him super safe. But lately, he is dealing with a major fail: he could not save his parents from getting a divorce. Now, his parents are living on two separate floors of their apartment building, and Portico is stuck in the middle. He is never fully with one parent or the other; he is just in-between all the time. To make matters worse, the elevator is busted, which means he has to dodge the stairwell bullies every time he travels between floors. When Portico and his best friends discover an empty, unlocked apartment, they finally have the perfect secret hideout. They decide to make it their own with some epic drawing stunts. But their new hangout starts giving the grown-ups some serious worries, and Portico is not sure if his superhero skills are enough to save the day this time.
