On the spur of the moment, 30-year old Alain gives up his well-paid job as a tester of computer games, but is uncertain over what do next. He takes up the offer of a place on a course to learn how to operate a bulldozer, although this means spending time away from home. During his training, he is paired up with a child-like younger man, Manu, who is passionate about wanting to drive a bulldozer but has no aptitude for the job. While his marriage starts to fall apart, Alain finds himself becoming more dependent on his relationship with Manu.
