Beetle and Caterpillar are best friends. Every day, they sit together on a big rock, sharing a picnic and looking out over the forest. But one day, Caterpillar goes missing and Beetle cannot find her.

Beetle sets out on a long journey through the forest, but Caterpillar is nowhere to be seen. Beetle's just about to give up when a friendly (and rather familiar) butterfly appears out of nowhere. Can it be Beetle's friend? She may look different, but the love they feel for one another is the same as ever.
