Marble likes to collect insects and loves to eat. Albert wants to be a scientist and has an old broken down convertible from his dad, that he wants to transform into an extraordinary machine.

That night, Marianne`s doll Lucy comes to life. When she suggests setting off to collect comet glitter together, the group can hardly believe their ears. The three kids think it sounds like fun and, together with Lucy and Albert`s machine, they fly into space, where they are in for a fantastic adventure.
