Charley Maplewood has never been one for parties – that would require friends, which he doesn’t have. Well, unless you count his monster friends, but they’re only imaginary. But now that he’s turning ten—the big one-oh—he decides to throw a birthday party for himself, complete with a “House of Horrors” theme. Of course, things don’t work out as he plans. Will Charley be able to pull it together before the big one-oh . . . becomes the big OH-NO!?

Based on the beloved book, The Big One-Oh! features lyrics by Academy Award-winner Dean Pitchford (author of the novel, Footloose), music by the acclaimed Tony-winner Doug Besterman (Elf, Young Frankenstein), and a book by iTheatric's award-winning playwright Timothy Allen McDonald (Roald Dahl's Willy Wonka, James and the Giant Peach).
