Chef Ramsay surprises the contestants with a rockin' performance from Grammy Award-winning guitarist Steve Vai, to illustrate the similarities between musicians and cooks in their ability to make magic with just one instrument. For this week's team challenge, the contestants are tasked with creating five unique dishes, each only containing 7, 6, 5, 4 or 3 ingredients. The winning team is rewarded with a friendly game of paintball, while the losing team must stay behind to participate in a grueling delivery day at Hell's Kitchen. Later, actor Jonathon Lougram ("Grown Up") and actress/TV host Garcelle Beauvais will make celebrity guest appearances at the dinner service prepared by the two teams. Tune in to see which contestants give award-winning performances and whose communication skills fall flat.
