A generation removed

In the United States of the bleak and menacing near future, teenagers have taken over the running of the country. The all-powerful young have enacted laws that mandate retirement at the age of fifty five. From that point on, geriatrics, or Gerrys as they're called, lose all access to social services, health care, and medications. They undergo regular, mandatory physical examinations. Any elder found to be the slightest bit infirm undergoes euthanasia. Mobile death vans, the dreaded Euth Wagons, patrol the streets, picking up the elderly for testing, executing them on the spot if they're in less than perfect heath. The callous and murderous attitude of the young toward the elderly sets in motion a frightening revolution, an epic struggle, a literal battle of the ages. Young against old. The raw, unbridled energy and arbitrary whims of teenagers against the wisdom and thoughtfulness of experience.
