The spaceship Cynro has received a distress call from the planet TEM 4. The crew tries to respond but ends up crash landing on the planet as a result of radio waves. Emerging from the ship, the crew is brought to the planet's leader Ronk (Milan Beli), who tells the Cynro crew that there was never any accident and that the distress call was all a mistake. As an apology he invites the crew to a party, much to the misgivings of Suko (Alfred Struwe), the ship's navigator. Sensing that there is more to Ronk's claims, Suko refuses the invitation.
