[...] Emil is trying to win his ex-girlfriend back. After observing two guys diving off a bridge into the Alster (a river flowing through Hamburg), he gets an idea: secretly following the girls to the park and having Max call Isabella with the news that Emil suffered fatal injuries from jumping off a bridge. [...]
Meanwhile, Oskar, Emil's twin brother, and his best friend Bruno are on set of their show and about to shoot a scene with Danish actor Roland Møller. As usual, they are planning to improvise their parts, but their director warns them that Møller has no tolerance for such shenanigans. Bruno makes an attempt to run through the script, but when Oskar eyes a pretty extra, they decide to flirt with her instead. Consequently, they are completely unprepared for their scene, making Møller angry. They are granted a five-minute break to learn their lines, but realize it's hopeless. Luckily, Isabella calls Oskar to inform him about Emil's "death". While they immediately figure out what he's up to, they decide it makes for a good excuse, so they tearfully inform the crew of the tragic news. Everybody is shocked and agrees to give them time off, and Møller goes as far as gifting Oskar his necklace, a present from his late wife.
Leo has sex with Jonas, then excuses himself as he has to help his boyfriend Florian move. They drive to Florian's new apartment, where they meet his new roommate. To Leo's horror, it's none other than Jonas, the guy he just cheated on Florian with. He desperately tries to talk Flo out of moving in with him, but can't come up with any convincing argument. Out of options, Leo then claims that he has realized he wants Flo to move in with him instead, a decision he immediately regrets when Flo enthusiastically agrees.
In the end, the five of them meet up, with Emil, Leo, Bruno and Oskar actually making the jump off the bridge. Unfortunately, Roland Møller passes under it with his kayak just when Oskar and Bruno take the leap. Seeing both Oskar and his very alive twin, he flies into a rage and throws their paddle at the guys as they are about to flee.
