One day, David (Jonny Weston) found the relics of his father, a scientist, in the attic - a camera and a set of drawings. What shocked David was that the contents of this set of drawings were actually related to how to build a time machine. He called his sister Christina (Virginia Gardner), his friends Quinn (Sam Lerner) and Adam (Allen Evangelista), and his crush Jesse (Sofia Black-D'Elia), and the five of them worked hard to actually build a time machine. Using the time machine, David and his friends frequently went back to the past, making up for the big and small regrets in their lives, and realizing all kinds of fantasies in their minds, but as time went on, David discovered that what they did could cause the Earth to explode.
