Grandpa's in the hospital and hating it, and makes trouble for everyone. Dad finds it too stressful to visit, but Gottfried Junior visits Grandpa as often as he's allowed, and when he's not allowed, he goes anyway. Grandpa thinks only of the place he was happiest - the island where he lived with Grandma. He wants to go back one last time, but they won't let him out of the hospital. Gottfried Junior and Grandpa take things into their own hands. If running away is the only way to the island, then they'll be runaways. Gottfried Junior thinks of everything. His lies are so good that when he decides to tell the truth, no one believes him.
