Investigators trace how money donated in Germany ends up funding Islamist extremist networks in Syria and beyond. The film follows a young German woman who returns home after living with the Islamic State, and she describes how funds were collected, moved, and spent inside the group. Reporters reconstruct the chain of middlemen operating in Germany and Austria who channel donations toward such causes, including money that reaches Hamas, tracking transfers that move through bank accounts, donation associations, online payment services, and cryptocurrency wallets. The team asks why German law enforcement struggles to stop these flows while investigators in other countries have had more success, pointing to legal loopholes that let small, seemingly innocuous donations accumulate into significant sums. Interviews with investigators, former extremists, and researchers build a picture of a financing system that operates largely in plain sight. The film argues that even modest donations, multiplied across networks, can underwrite violence far from where the money originated.
