Stagefright Chameleon (1988)

A solitary figure walks a railroad bridge. A spectator watches from overhead; he corners the figure to hand him a card saying, 'Don't give up hope.' The figure retaliates with a video camera, filming the spectator. In the distance, they see a woman and follow her into what seems to be, from the outside, a small building, but once inside they're in a labyrinth that takes them to the lair of the Mole King.

Unfortunately the movie Stagefright Chameleon is not yet available on HBO Max.
