[3] The quiet-natured Kelia has just joined a prestigious business school in France (some media will consider this to be HEC Paris).

[4] At a party, she meets Dan, an unpopular second-year student whose intelligence is ruled by a cold assessment of the commercial value of every thing.

Kelia and Dan then engage a young woman and pay her to accompany Jaffar to a soirée in order to increase his seductive capital with the girls at the school.

The sub-heading of the film refers to their respecting the rules of the marketplace; they rent young people to attend parties.

Kelia, who pretends to be a lesbian with her friends, is attracted to Louis, who is confident of his charm, unlike Dan.
