Teenage David Raskin is a genius who dreams of attending MIT. He has a crush on Jessie Pierce but is too shy to date her. When he finds the design for a time machine that belonged to his father, he decides to build the device with his friends Quinn Goldberg and Adam Le, and his sister Christina. Soon Jessie joins the group and becomes David's girlfriend. When their experiment gets out of control and changes the future, David decides to fix the problems but only makes them worse.—Claudio Carvalho, Rio de Janeiro, Brazil
