The Egyptian adventure comes to a thrilling close! In the finale of **“ALL or NOTHING,”** idols **Johnny** and **Shindong** step up for the toughest challenge yet — a high-stakes mission combining swimming, math, and pure teamwork, with tickets to Cairo on the line.

### What’s the Show About?

“ALL or NOTHING” is a winner-take-all travel variety series set in Egypt, where the cast spends seven days and six nights competing for the title of “prince” across Cairo, Luxor, and Hurghada. The lineup features SUPER JUNIOR’s Leeteuk and Shindong, DAWN, WEi’s Kim Yo Han, and NCT’s Johnny and Jisung.

### The Final Mission: “Mermaid Prince’s Math Class”

After spending the whole trip competing against each other as “princes” and “paupers,” the six members finally set their rivalry aside for one last group mission in the middle of the Red Sea. The challenge: one member dives underwater in a submarine to identify Egyptian numerals, relays them to teammates above water, and the group must calculate the numbers to crack a safe’s combination.
