Music by Pedro Bromfman. Martin Sheen narrates this documentary that delves into the mystery of a 73-year-old nun's murder in the Amazon. THEY KILLED SISTER DOROTHY shows that the killing of this saintly woman was not a random act of violence; instead, the act was perpetrated by people who have the interests of their bank accounts, rather than those of the people and the rainforests, first in their minds.
