East Germany before reunification: Wolfgang Schulz watches Western television and discovers his long-lost twin brother Walter on the show "Aktuelles Sportstudio." They quickly get in touch, and the two decide to switch roles for a few days. Since both work in advertising, they think it will be a temporary bit of fun. But everyday life turns out to be different. Shortly afterwards, the Berlin Wall falls and the brothers found a company together. Now their different mentalities really come to the fore, and "Schulz & Schulz" have to realize that even in the general spirit of optimism, it is not so easy to run a company together. It doesn't take long before the two find themselves in the red.
