The final 10 chefs are surprised when Chef Ramsay brings in his daughter, Tilly, to celebrate her Sweet 16. During the challenge, each chef is tasked with creating a worthy dish to be served at Tilly's party. The team that gets the most dishes on her menu wins the challenge. While the winners enjoy time at the Malibu mansion, a member of the losing team requires medical attention after the pressure becomes too much. Meanwhile, after a difficult dinner service, a fan-favorite veteran winds up on the chopping block.

Both teams are down to four chefs each, as the competition continues to heat up. The dining room gets an Italian transformation for one of the most anticipated challenges of the season – the blind taste test. Hell's Kitchen then closes its doors to the public for a special charity dinner service, during which the two teams cook to honor supporters of St. Jude Children's Research Hospital and the Waterkeeper Alliance, with a new five-course Italian menu. The night turns disastrous when Chef Ramsay must step in and finish cooking for one team before a dramatic elimination.
