Rammbock (also Rammbock: Berlin Undead and Siege of the Dead) is a 2010 German horror film directed by Marvin Kren, written by Benjamin Hessler, and starring Michael Fuith, Theo Trebs, Anka Graczyk, and Emily Cox as survivors of a rage virus in Berlin. Besides its native Germany, it was theatrically released in Austria, the UK, and the US. Plot Michael, who has recently broken up with Gabi, visits her Berlin apartment to return her keys and hoping to save their relationship. He finds two repairmen there, but Gabi has gone outside and they do not know where. As Michael attempts to contact Gabi, a rage virus transforms people into bloodthirsty cannibals, and the older repairmen attacks Michael. As Berlin falls into chaos, Michael and the younger repairman, named Harper, barricade themselves in the apartment complex and brace for an attack. The pair attempt to make contact with the other inhabitants of the apartment complex. Following news reports, they find out that the rage virus is only activated after the victim undergoes agitation or adrenaline, and it can be subdued by remaining calm or using sedatives. Michael makes a deal with another resident to retrieve some sedatives from another apartment which the resident needs for his sick wife. Michael eventually stumbles upon Gabi but he finds out that she is in another relationship with her neighbor and it was her reason for breaking up with him. Harper discovers that the infected are photosensitive to camera flashes. Michael, Harper, and another resident, Anita, attempt to break out of the apartment building using cameras and flood lights but are forced to abandon Michael who reveals he has been bitten. Michael quickly helps Harper and Anita attach the cameras to a bicycle so they can pedal to the harbour and use the camera flashes to ward off the infected. Michael remains behind in the square and realizes that he has a sedative left and if he takes it there is a chance he may not transform. However just as he is about to take the sedative he sees a now-infected Gabi emerging from the building. He decides not to take the sedative and transforms just as Gabi is about to attack him and the two embrace. Harper and Anita make it to the harbour and escape on a boat.
