Ilsa, the Tigress of Siberia is a 1977 Canadian sexploitation prison film that serves as the third sequel to Ilsa, She Wolf of the SS.
Dyanne Thorne reprises her role as the title character, but in this installment, Ilsa, referred to as "Comrade Colonel," oversees a 1953 Siberian gulag that mentally and physically breaks down male political prisoners in the waning days of Stalinism.
The B-movie website Nanarland noted that the film offers in fact 2 films in one; the reviewer also found the film less "dirtyâ than its predecessor but âÂÂsillierâÂÂ.
