Dorami and Doraemons (except for Doraemon, who is absent) are in space to visit an amusement park called Space Land. However, upon arriving at the entrance they are sucked into a huge vortex, and their spaceship gets destroyed. Once in the park, they suffer other hardships, until they discover that an evil monster has organized everything against them. Again, Dorami and the Doraemons must intervene so that justice can triumph. ~ translated from the Italian wikipedia
