A small circus arrives in a coastal area of the North Sea: the place looks rather eerie and the audience is quite scarce. But despite all of this, the life of the performers is animated by feelings born under the circus tent, and which are often lived out in the secret of their trailers. The ballerina Angèle has an affair with Elliot, the company's clown who is tormented by his conscience; but she is also courted by Heroy, the circus director; he is a cruel and potentially dangerous man who is willing to win her over by resorting to the powers of the magician Zephyr.
