Ilsa, the Tigress of Siberia, is a sexploitation "men in prison" style film produced in Canada in 1977. It 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.
