Kid With a Bike (2011, Those Dardennes)

Kid does not have a bike, and lives in a group home but keeps escaping to look for his dad, a sous chef who sold the bike and doesn’t want to be a dad anymore. Enter large-hearted hairdresser (and Haute Tension star) Cécile de France, who takes a liking to the boy (even though he’s a bit of an asshole) and buys his bike back. Gaining a new mother-figure is outweighed by Dad (Jérémie Renier, naturally) telling him not to come around anymore, so Kid immediately gets mixed up with a gang of criminal youths. He stabs Cécile when she tries to keep him from going out to conk a newsseller with a baseball bat. The newsseller takes revenge, but everyone is alive and intact in the end, and Cécile remains large-hearted despite having to pay back the money her shitty adopted son stole. The Kid would go on to play Jean Renoir’s little brother in a biopic.
