Come Dine with Me sets sail for Guernsey. Island FM radio boss, Mike Huston, kick-starts the week with an evening of 'spice and taste'. Used to being the man in charge, he's less than impressed when his evening is hijacked by 20-year-old entrepreneur, Ben Inder, who thinks he's the best thing since sliced bread. On the second night, fashion designer Kay Davidson dons the oven gloves and tries to impress with a fine dining menu and a sophisticated wine tasting game. Once again, Ben upsets his fellow diners, particularly feisty foodie Gemma Sparkes, when he tries to play wine connoisseur. She soon takes him to task over his arrogant attitude. On Ben's night, guests can't wait to see if he can actually 'walk the walk' and are eager to find flaws. Mike pounces on this opportunity to show Ben who's boss. Taking the spotlight on the final night is wannabe chef Gemma. Her guests feel she's the dark horse of this hotly contested competition, but will she do enough to snatch the prize from her rivals?
