Home improvement queen Mona Nagel can't believe her eyes: her boss Timmermann's newly acquired finca on Mallorca, which she was supposed to "renovate" with just a few simple steps for the media, is a construction site. There is more to do here than Mona had expected. Under the watchful eye of photographer Max, the successful guidebook author and advertising figure of appliance manufacturer Timmermann is to open up the Spanish market for the family business with her campaign, which will culminate in a major press conference. What neither Mr. Timmermann nor Mona's publisher know: The "do it yourself" woman can't even screw in a light bulb properly. Wallpapering, painting or sanding wooden floorboards are bohemian villages for Mona. Now the misery is great, and Mona tries to hide her little to non-existent manual skills - and not just from the team of craftsmen hired by her boss and led by Lars.
