Farcial action fun with Bertil and Hugo, who do menial jobs at a big city hotel. Bertil is about to marry and has put money aside for his bride's morning gift. Only Hugo has kind of borrowed the money and blown it all on a wrong bet in a pigeon race. Together, they obviously have to get rich quick. When a diamond seems to be lying around for the taking, the hotel is virtually on its head.

Don Fefe vil sælge den store diamont Casanova for at indfri sin gæld. Samtidig, i Danmark, drømmer Bertil om ægteskab med Gurli. Problemet er bare, at Hugo har spillet hans opsparede penge op. De stjæler en taske fra Marcello, som indeholder Casanova. Don Fefe har dog opdaget hvem der har stjålet fra ham. Albin er dog klar til at tage kampen op med internationale forbrydere. Undervejs bliver Hugo forelsket i Eva. Albin klarer dog ærterne, således at Bertil og Gurli kan blive gift.
