Wild in the Streets(1968)

If you're thirty, you're through!

Musician Max Frost lends his backing to a Senate candidate who wants to give 18-year-olds the right to vote, but he takes things a step further than expected. Inspired by their hero's words, Max's fans pressure their leaders into extending the vote to citizens as young as 15. Max and his followers capitalize on their might by bringing new issues to the fore, but, drunk on power, they soon take generational warfare to terrible extremes.
