A passionate ukulele player, cartoonist Joann Sfar ("The Rabbi's Cat") flies to Hawaii to explore the history of the little instrument, as well as the culture that surrounds it. For the pocket guitar, imported in 1879 by the Portuguese from Madeira who had come to harvest sugar cane, is the vector of a philosophy specific to the archipelago: the spirit of "Aloha", which condenses hospitality, joy, love and respect. With brushes in hand, Joann Sfar set out in search of the ideal instrument, meeting craftsmen, musicians, dancers and guardians of Hawaiian culture.
