On January 7, 2024, six sailors set off from Brest, the city at the edge of the world, aboard flying trimarans for the Arkea Ultim Challenge, a bold and risky round-the-world race. Among them is Anthony Marchand, with the smallest of the biggest boats. Though not as renowned as others, Marchand's team is ready to prove that even the underdogs can dream big, especially as their boat has already set a world record. In this ultimate challenge, anything can happen.
