If It Don't Fit, Use a Bigger Hammer

If It Don't Fit, Use a Bigger Hammer (Was nicht passt, wird passend gemacht) is a 2002 German comedy film directed by Peter Thorwarth.

Plot
Kümmel, Kalle and Horst work for the contractor Werner Wiesenkamp, who runs a small construction company in Bergkamen in the district of Unna. Since Kümmel, Kalle and Horst are underpaid, and their boss lives large, the three employees persuade the boss on his garden party to hire Marek, a Polish illegal worker. However, Wiesenkamp sets up the young architecture student Philipp as an additional worker (much to Horst's unwillingness), who actually only needs an internship certificate for his new employer in Asia. Philipp hopes to get this certificate without real work, with the help of his uncle, a city councilor.

The following day Philipp appears on the construction site, still assuming that he only has to wait for Wiesenkamp's signature. First, however, he lands on the neighboring construction site, run by Wiesenkamp's brother Ernst. The misunderstanding is cleared up and the foreman Jochen brings Philipp to the correct construction site. While the first construction site was professionally run, the second is an improvised mess. However, until Wiesenkamp arrives and brings Marek, Kümmel, Kalle and Horst assume that Philipp is an additional worker. Horst, in particular, harasses Philipp at every opportunity.

Philipp is given the task of securing scaffolding, but instead tries to rebook his flight to Kuala Lumpur. Kümmel, Kalle and Horst stage Marek's death by falling down from the scaffolding, and ask Wiesenkamp to pay for their silence. Philipp, who sees himself as guilty of Marek's "accident", calls an ambulance, but when it arrives at the construction site, there is no indication of an accident.

After work, Kümmel, Kalle and Horst pretend to dismember Marek's "corpse" and bury it on the construction site. Philipp is in the meantime inconsolable. That evening, Kümmel, Kalle and Horst celebrate at Horst's home – where Marek is also present and gets his cut. Here it is clear that Marek is not dead, but instead is conspiring with the others.

During the celebration, Philipp appears to Astrid, Horst's daughter, who worked on Wiesenkamp's garden party and also studies architecture. Astrid came "by accident" past the construction site to ask Philipp if he could help her set up her new computer. Horst, who is not enthusiastic about the approaching relationship between his daughter and Philipp, throws Philipp more or less friendly out of his house, not without him on the doorstep still something to say. During the conversation Marek comes in the background, but is not seen by Philipp. This is just the beginning of a series of scenes in which Marek can be seen again and again, mostly in premises that Wiesenkamp also visits.

Meanwhile, the company is in financial difficulties, but the three employees and intern Philipp are willing to finish the construction project to help their boss Wiesenkamp out of financial distress. For example, they use asbestos insulation, which Kalle gets for free from his brother-in-law Siggi, who works in a hardware store.

However, while digging, the four find an unexploded World War II-era aerial bomb. Instead of calling the bomb squad, Kümmel, Kalle and Horst decide to re-bury the bomb and simply build the foundation one meter shorter than planned in the blueprint. Here, Philipp can score: In a nightly meeting on Astrid's computer, he not only fakes the blueprints, but also gets closer to Astrid.

Thanks to Philip's help, the construction project can continue as planned, and the initial teasing stops abruptly. To celebrate this success, visit Kümmel, Kalle and Horst together with Philipp the red light district. While drunk, Philipp tells a prostitute about the dead Polish. However, when Werner Wiesenkamp's wife and his brother disappear to Majorca, things take a dramatic turn.

The next morning, Astrid visits the construction site to ask Philipp why he did not attend her appointment. Horst tells his daughter that Philipp was with him and the others in the brothel. Werner Wiesenkamp, who is also a sports pilot, discovers at the airport that Marek is still alive, whereupon he joins the Construction site drives to confront its employees. Meanwhile, a police operation is taking place on the construction site, as the police prostitute has told Philipps story. The forensics found in the foundation of the plastic bags that were cemented by Kümmel, Kalle and Horst after Marek's accident. However, the bags contain only several cans of used oil and not, as assumed, the dismembered corpse of Marek. The construction site is then closed by the authorities.

Kümmel, Kalle and Horst are hired by Ernst Wiesenkamp, Werner's brother, but released shortly thereafter. Meanwhile, Werner Wiesenkamp plans to mount the aerial bomb from the construction site under his sports plane and "put it on his roof" for his brother. Although Kümmel, Kalle, Horst, Astrid and Philipp can successfully prevent this project, they do not, however, detonate the bomb when handling the excavator. The explosion uncovers a disused mining tunnel that leads from Werner Wiesenkamp's construction site to the adjacent construction site of Ernst Wiesenkamp. Caraway, Kalle, Horst, Philipp and Werner unceremoniously tear in the old mining pillars.

Back in the daylight, they discover that the topping-out ceremony is on Ernst Wiesenkamp's construction site, and Werner tries to stop his brother. However, Ernst is not persuaded, and when the weight of the tree is added to the house, it collapses. Therefore, the contract for the establishment of the kindergarten not serious, but to the company "Marek and Partner": Werner Wiesenkamp has reconciled with Marek, who has become rich in the meantime by stock trading. Both have allied themselves professionally, whereby Werner's construction company is rehabilitated. Philipp and Astrid are happy together, while Kümmel, Kalle and Horst work again for Werner Wiesenkamp.
