Friendly aliens land in your back yard and take you for a ride. It's amazing and afterwards they tell you to tell the governments of the (western) world to come join them. You do so and they take them on a ride in a spaceship. There it turns out they're just ordinary crooks bent on world domination and now they've kidnapped the worlds leaders.
Actually, that's a comic book. I wish I won't get sued for plagiarism
