Rachael explains that this week's cooking showdown is based on an issue that many families face at one time or another: what do you do when you need to feed a family of four at the last minute, and you don't have time to go to the grocery store? If you could only run to the corner convenience store, could you come up with a nutritious meal? With the premise for the challenge laid out, Rachael lets the contestants loose for a shopping spree in her make-shift convenient store, "Ray-Mart." The clock is ticking as the cooks race to fill their carts with as many ingredients as they can, keeping in mind that their mission is to create a balanced, family-style meal highlighting one of the Ray-Mart items in only 30 minutes. And this time, Rachael will not be judging their work -- surprise chef Rocco DiSpirito has the power to end the journey of one contestant! "In addition to fair play," Rocco tells the contestants, eyeing Marvin, "I am looking for a well-balanced, nutritious meal, obviously with a very creative use of everything you find at Ray-Mart, and it's gotta taste good -- it's gotta taste really good above all." After snatching their ingredients off the shelves, the contestants race to the prep kitchen to make a do-or-die meal! Does Marvin have more tricks up his sleeve?
