I remember that the intertext of the film took elements from the legend of the King Arthur, like it happened but now is the future, at some point the protagonist maintained relations with the villain of the film so she could steal from him the chalice of the inmortality, she tried to kill it without success, he punch her and procede to drink from the chalice, regaining his health, Forward in the movie the protagonist kills the villain by breaking his neck, but the real bad guy was an escort of her, there is another small guy who comes with the girl and the guy,  he takes the chalice and flies out of earth into space. the film or episode has colors, its really graphic about the violence.
