This video is a mashup between multiple Star Trek episodes and the three original Star Wars movies. It's about 7 minutes long and pretty well done. The Star Trek Enterprise is warping along when it comes upon the Death Star. The Enterprise tries diplomacy and the Empire from Star Wars attacks straight away. It has Tie fighters attacking the Enterprise and the Enterprise bringing down a Super Star Destroyer. Finally the Enterprise has to run away when the Death Star fires on them. The video mashup itself is pretty well scripted with the dialog all matching and making sense in the 7 minute plot.
