Synopsis of Five Weeks in a Balloon
In Five Weeks in a Balloon, Professor Ferguson plans to demonstrate the practicality of his new hot air balloon design by charting the unknown areas of Africa – but the government wants him to claim the area to prevent slave trading from being established there. His crew consists of his friend Jacques, a retired general, and a journalist — and along the way they pick up two escaped slaves and a slave trader as well.
