Four old widowers gather in a village pub once a week to share their frustrations with modern-day living and their increasing sense of impotence in a world that is not as they'd like it. On one of their visits, they learn of the suicide of a local farmer, brought about by his despair at having to deal with repeated instances of fly-tipping on his land. With the authorities seemingly unable to bring a stop to this countryside scourge, the four old codgers decide not to simply accept their status as powerless observers, but instead to actually do something. That is, they decide to become vigilantes - with one specific objective in mind: to capture 'in the act' whoever is responsible for the fly-tipping. Little do they know, when they make this decision, how it will affect their shared sense of impotence or to where it will ultimately lead them.
