[3] Grégory Van Huffel, called Greg, is the head of Alibi.com, an agency for cheating people.

While his company is growing successfully, Grégory falls in love with Florence, who, due to bad experiences, considers honesty to be the greatest good in a relationship.

During a trip to their parents' country house together, Greg discovers that Florence's father Gérard is one of his customers at Alibi.com.

While Florence's mother, Marlène, assumes that her husband is on a business trip, Gérard meets with Cynthia in a hotel in Cannes.

In the end, Gérard and Greg become repentant sinners, while Cynthia publishes Alibi.com's customer list on the Internet.
