Die Frau des Schläfers(2010)

Overview:

Karla works in a call center. She marries Zaid Yakin and has a happy marriage with him. Even the death of her father-in-law gives Karla no reason to doubt the perfection of her family, until one night she discovers that her husband and son Hamy have disappeared without a trace. Shortly afterwards, she is made privy to the ongoing investigation by officials from the Federal Intelligence Service. It seems that her husband has returned to his home country, Sudan, to plan a terrorist attack. Karla travels to Africa to look for her son disguised as a Muslim woman wearing a burka and finds out that Zaid has been lying to her from the start: his relatives are by no means destitute, but arms dealers. He himself is a "sleeper" and is supposed to sacrifice himself as a suicide bomber: his target is the Christmas market...
