 Whilst Tom Paris along with Harry Kim are running one of there holodeck programs voyager get caught in a layer of sub space. However this layer of sub space or a  sub space sand barge  as it is knick named is home to a race of holographic aliens, but there is one big problem they are not able to detect voyager or any carbon based life forms (humans) instead they transport down on to the holodeck and start a war with Dr Chaotica s army of Evil!!!! When Voyager detects internal weapons fire on the holodeck Tom Paris and Tuvok are dispatched to find out what the problem is. When they arrive on the holodeck tom Paris immediately notices something is wrong in that one of the  good guys  his secretary Constance Goodheart is dead this is strange as he puts it  the good guys never die . However they find Satan s robot and after some minor repairs and Tuvok commenting that  Mr Paris you knowledge of this technology is impressive , the robot informs them that there are intruders from the fifth dimension who came through a portal. Tuvok is able to verify that the weapons signature coming from the  portals  matches the weapons signature that they detected. before they leave Paris insists on checking his rocket ship as it has sensors of a type, while deciphering 20th century technology a holographic alien enters the ship and does not believe what Tuvok has to say as he cannot detect them as they are not holographic life forms, Satan s robot then attacks him causing him to drop his  calling card . While they are on this little re-con sense mission Janeway, Torres and Seven are in the Astrometrics lab. Janeway comments that this reminds her of a previous mission when she was a science officer on the Alabotoney  we spent three days spinning our wheels before we realised that our own engine emissions where  seven of nine literally takes the words out of her mouth apparently if they lower there emissions then they will be able to get out. Paris comes up with a plan to deal with Chaotica which Captain Janeway who seems to find slightly amusing. Paris suggests that they allow the story to play out with a bit of help from the Voyager crew, all they have to do is do disable the  death ray  Tuvok then comments that  it s a pity that we don t have one . Paris then manages to convince a reluctant Captain Janeway to play the part of Arachnia Queen on the spider people as it will allow them to infiltrate Chaotica s fortress of doom as he has been looking to create an alliance with the Queen. A more enthusiastic EMH is willing to take on the role as president of earth in order to get the aliens to stop firing so that Paris (Captain Proton) and Harry Kim can disable the Death Ray. As the doctor is holographic they believe him because basically they can detect him! But even these best laid plans never go according to plan; Janeway is tricked in to confinement rings after persisting that the lightening shield be taken down makes Chaotica suspicious of her. However she is unable to un corps the pheromones a powerful potion that was given to Chaotica by the real Aracnia, the potion sends the smeller crazy. Lonzac then realises Janeway from her bonds allowing her to turn off the lightening shield and Paris is able to disable the lightening shield. But is this then end of Chaotica? Voyager is then able to move off this  sub space sand barge  and continue on her mission to get home.
