Anders er kørt fast i ægtesengen, men får hjælp fra sagnhelten Orion, hvis råd dog bestemt ikke er up-to-date. Det hele bliver værre, da den gamle liderbuk fatter interesse i Anders’ kone. Spørgsmålet er nu, om de kan genfinde gnisten.

“Anders, dit ynkelige skvat! Lyt nu til en rigtig mand. Lad mig, den smukkeste af alle dødelige give dig et råd!”

Anders er frustreret, liderlig og fyldt med mindreværd. Sara vil bare sove, høre sin podcast og blive klar til sin nye kunstklasse. Orion, den gamle jæger og liderbuk, ser træt til fra stjernehimlen nat efter nat. Snart skal alting ændre sig.

Under Orions Bælte er et erotisk lystspil og en romantisk komedie om ægteparret Anders og Sara, der er kørt godt og grundigt fast i ægtesengen, men får hjælp fra sagnhelten Orion. Scenariet har en fast historie og er sat i faste scener, hvor det sjove ligger i skiftende roller, misforståelser og liderlige hentydninger. Spillerne har ingen faste roller. De skifter i stedet fra scene til scene, så spillerne i fællesskab former hovedpersonernes frustrationer og halvkvalte forsøg på nærkontakt.

Selvom scenariet handler om liderlighed, erotik og et akavet parforhold, er der kun begrænsede mængder af reel sex med i scenariet. De fleste scener spilles semilive, mens erotiske situationer simuleres med famlende nakkemassage og kiksede dialoger.

Anders is aided by the mythical hero Orion, when he finds that his marriage has become way too sexless. Unfortunately the old perv’s advice is not all quite up-to-date, and things get worse when the old lecher takes an interest in Anders' wife. The question now is: Can they reignite the spark?

"Anders, you sad existence! Listen now to a real man. Let me, the most beautiful among all mortals, give you some advice!"

Anders is frustrated, horny, and filled with insecurity. Sara just wants to sleep in sleep in peace, listen to her podcast, and prepare for her new art class. Orion, the old hunter and womanizer, gets more and more tired og, night after night, watching it all from his constellation in the sky. Soon, everything is about to change.

Under Orion’s Belt is an erotic farce and a romantic comedy about Anders and Sara, a married couple thoroughly stuck in a sexless routine, who suddenly get help from the mythical hero Orion. The scenario has a fixed storyline and is set in pre-defined scenes. The humor lies in changing roles, misunderstandings, and lustful innuendos. Players don't play fixed roles. Instead, they switch roles from scene to scene, collectively shaping the frustrations of the main characters and their half-hearted attempts of getting intimate.

Although the scenario revolves around lust, eroticism, and an awkward relationship, there are limited amounts of actual sex scenes involved. Most scenes are played semi-live, while erotic situations when they occur are simulated through clumsy neck massages and awkward dialogues.
