Chaos theory tells us that small changes in initial conditions can result in significant changes later, like the flutter of a butterfly’s wings might cause a typhoon halfway across the world.  In terms of time travel, it’s called a time paradox, and it’s the very thing that keeps DeeDee from trying out her new time machine she’s invented using household items, including her sister’s curling iron. 

Unfortunately for DeeDee and her friends — and for the state of all mankind, really — Tony didn’t pay enough attention in school last week.  He’s flunked his algebra test, so he dismisses DeeDee’s warnings and borrows the hat-shaped time travel device for a quick trip back to last Thursday to warn past Tony, in hopes of saving his current self from summer school.  But he changes a little too much, so he goes back again...  and again.  Soon, Tony finds himself returning to an increasingly bleak and ultimately apocalyptic world where everything he ever knew is gone — or dramatically different. 

Oh, and did we mention the zombies?!  Can Tony find a way to make everything normal again?  Only time (travel) will tell in this absurd one-act!
