Four chefs visit Flavortown to tackle Guy Fieri's worst grocery list yet, featuring ingredients they'd never dream of putting in the same dish. The chefs must use every item on the list during the three rounds of competition or face elimination, but Guy adds lots of extra twists. The chef with the skills to turn the groceries on Guy's worst list into the best dishes earns a shopping spree worth up to $20,000.

Guy Fieri loves any excuse to bring chefs from Diners, Drive-Ins and Dives to Flavortown, so he welcomes a few chefs and their moms for a Mother's Day competition. The DDD chefs are forced to watch as their mothers shop from the chefs' lists, and then the store closes as the chefs are in the middle of their shopping. In the end, one mother-chef duo wins up to $20,000 in a Flavortown shopping spree.
