She first appeared having sex with Bletch the Walrus. Bletch suddenly hid Samantha in the safe while he talked to Heidi about Trevor insulting her.

After Heidi was heartbroken about Bletch dumping her, Heidi attempted to kill herself with a machine gun, but Samantha walked in and insulted her again. Enraged, Heidi said, "Eat lead, you man-stealing slut!", and shot Samantha, killing her.
