Iguchi is one of her callers at the counseling center, we learn, someone she helped. He wants to return the favor. His plan is to blackmail her with his pictures into doing exactly what she wants to do anyway, but doesn't have the will to conquer her repression and do openly. Her fear of disrupting her marriage, shocking her husband — her repression — forces her to follow Iguchi's plan.

What follows is the erotic liberation of Rinko and her husband Shigehiko, after a torturous path of humiliation, voyeurism, curiousity, conflict and, ultimately, release. The film's very structure parallels the sexual act itself. We are seduced, violated, seduced again, then taken to climax.

All of this is presented through the lens, Iguchi's and Tsukamoto's. Literally, it's a movie drenched in voyeurism, just as the city itself is drenched from beginning to end in rain.

A Snake of June is all about fighting through the alienation and separation of modern city life. The film makes extensive use of static framing shots to set scenes or introduce characters. There are also a lot of circular openings — eyes, windows, cones — through which we see. Characters often hide around corners to watch other events unfold; there are frequent shots of background characters watching the main three in action, staring directly into the camera as though we are Rinko or Shigehiko.

Outside of their marriage, we see Rinko or Shigehiko interact with others, especially Iguchi the blackmailer, through the telephone. Other important moments come through the phone. As much as we see these three out in the world, they don't have much interaction with it. In fact, they own an observatory and a large telescope, the better to disconnect and turn their attentions elsewhere.

One stunning sequence involves Rinko being forced to wear her too-short skirt sans underwear through a department store. Her fear is so intense she dons a pair of dark glasses and clutches her umbrella in front of her, like a shield. Add to that her halting, fearful steps, knock-kneed to protect her sex, and she appears almost like a blind woman. Given that she's being led by Iguchi to her release from inhibition, that's a powerful metaphor. The sequence is shot with rapid cuts and shaky, too-close hand-held cameras, to help convey her fear and disorientation. When Iguchi next forces her to buy and insert a vibrator as she parades around the city, Rinko's all-consuming response is truly climactic, orgasmic. Her odyssey is sexual in both form and conclusion!

The counterbalancing theme is water. It pours, cascades, drips, splashes, pools and roars through A Snake of June. It's a metaphor for sexuality, the unstoppable pervasiveness of desire. In nearly every outdoor shot, it's raining. Windows are always being spattered with it. Clothes are soaked in it; faces and bodies spotted. There is a repeated shot of water racing like a torrent across stones to a storm drain, collecting in a strange, Lynchian place in the bowels of the city.
