“Children's Library” is a series of excellent children's books with incredible stories, fairy tales and short stories. The fifty-eighth volume includes the famous novel by J. Verne “The Children of Captain Grant.” During a boat trip off the coast of Scotland, which he took on his yacht "Duncan" Lord Edward Glenarvan and his family, a hammerhead fish unusual for these waters was caught. A bottle containing a damaged written document was found in it. From the surviving part of the note, it is possible to establish that Captain Grant, a brave Scot and a famous captain, is asking for help. The official authorities of Great Britain refuse to help in the search for the captain - after all, the note was written two years ago, and the location of the crash is unknown, only an indication of the thirty-seventh parallel has survived... Then Lord Glenarvan himself goes in search of the captain with his family, the children of Captain Grant and the geographer Jacques Paganel, who accidentally joined them.
