Emma Watson and Daniel Brühl have signed on to star in Colonia, a thriller set during the 1973 Chilean military coup.

The plot centers on Daniel (Daniel Brühl), who is arrested by dictator Augusto Pinochet's secret police. Emma Watson plays his lover Lena, who tracks Daniel to a sealed-off area in the south of Chile known as Colonia Digignad. The government has set up a charitable mission run by a preacher as a front for this sinister place where no one escapes. In order to get Daniel back, Lena must join this cult.
