Guy Fieri invites four "burgermeisters" who think outside of the bun to test the boundaries of what a burger can be. First, he challenges each of them to pound out four heavy-hitting burgers using only six pounds of ingredients. Then, they slide "sliders" to select the unorthodox ingredient they must incorporate into both their cheeseburger and side dish. The best burger baller gets to shop Flavortown Market for up to $20,000.
