Jack Wrangler portrays a split personality, (thus the title Gemini), torn between the life of nasty, back-alley sex and his clean-living lover, Craig (Chris Adams in his first adult film role).

As the film opens, Jack lies in a hospital bed, having a conversation with his doctor and lover, Craig. The doctor reports that Jack is a "classic schizophrenic," but after the "final incident" they should be able to get rid of the second personality.

Next, in flashback, we see Jack in a leather jacket and torn jeans servicing leather-clad "daddy" Richard Locke in an alley. Locke smokes almost continually as Jack blows and eats him.

From here on, the movie alternates between scenes of Wrangler as Eric, the successful architect who falls in love with Craig, the sweet carpenter who works for him, and the aggressive loner persona, Jack, who's very much into cruisy, anonymous sex. One night, Craig sees Wrangler as his other persona, but Jack doesn't recognize him. At home, Craig questions him about his presence in the bar, but Wrangler claims to never go to the bars. Craig finally dresses up in leather and approaches Wrangler's horny alter ego, Jack. They start having sex and the screen goes black, with Wrangler again ending up in the hospital bed. Apparently having sex with Craig has helped Wrangler to lose his other ego. Other sex scenes include: Eric/Jack seducing a tool-belt wearing construction worker (Craig); Jack sucking off two thick dick men through gloryholes; Jack getting gang-banged atop a pool table; and Jack satisfying himself with a street hustler. The masculine men and themes are occasionally inhibited by older film footage, but Jack Wrangler appears in every scene and proves to be a credible star, both sexually and professionally. The opening and final segments are the same. No Condoms
