Consider a light beam incident from air to a glass slab at Brewster's angle as shown in figure. A polaroid is placed in the path of the emergent ray at point P and rotated about an axis passing through the center and perpendicular to the plane of the polaroid:

Consider the diagram, the light beam incident from air to the glass slab at Brewster's angle ( 
). The incident ray is unpolarised and is represented by dot (.).
The reflected light is plane polarised represented by arrows.
As the emergent ray is unpolarised, hence intensity cannot be zero when passed through polaroid.
