Ingrid (Jo Jo Deville) was a minor antagonist in the 1975 sexploitation film, "Ilsa: She Wolf of the SS". It was the first of four films in the line of Ilsa movies.
Ingrid was Nazi lieutenant serving under Ilsa (Dyanne Thorne) alongside Maigret (Sandy Richman) in a Nazi death camp and was just as needlessly cruel and sadistic as her commanding officer.
Under Ilsa's orders she and Maigret would run "medical" tests on the female prisoners to prove that women can withstand pain just as much as men.
In one brutal scene, two prisoners, one male and one female, are discovered talking, a violation of camp rules. The violators are bound nude, face down on tables and Ilsa watches as Ingrid and Maigret (topless and covered with a sheen of sweat) brutally flog the pair with cats-o-nine-tails. When the two are beaten to death, Ilsa orders her lieutenants to hang them up by the ankles outside for the other prisoners to see.
When a new American prisoner named Wolfe catches Ilsa's attentions, she decides to begin a sexual relationship with him, and also has Ingrid and Maigret have sex with him while she watches.
The men and women prisoners plot an uprising to escape. At the end, the prisoners capture and torture the guards before they eventually execute them. Ingrid is shot between the eyes.
