Forte Stollen and Ranpha Franboise, part of the Angel Unit, has been sent to a beach resort to find Baron Fitzgerald III (a cat that was heir to a large family fortune).
They find many cats that look like Baron III and capture them.
After many winnings and victories, the casino owner challenges Forte and Ranpha to a special roulette game of all in bet.
The casino owner rigs the roulette game to make him win.
On this day, the Angel Brigade is supposed to welcome their newest member, but Forte and Ranpha have gone on a vacation to a casino.
