During the reception, the fathers of the groom and bride exchange insults and a gun battle ensues in which many guests - and Les Dogs - are casualties though the happy couple escape. Victor, who has wandered in on the scene, is asked to take wedding photographs and has a series of dreamlike fantasies all based around his infatuation with Angela.
