Cherry Tree Lane (movie, 2010)

Prosperous professional couple Mike and Christine are settling in for a standard evening of wine, TV and low-level marital hostility when a ring on their doorbell changes everything. Turns out their son Sebastian is in a little trouble with some local boys, who are quite prepared to camp out and wait for him to get home ... the resulting culture-clash chamber drama is raw, revealing and nerve-splittingly tense.
