Brief Explanation

This commercial features a man gargling continuously in a range of scenarios throughout his day. The voiceover tells us that, for lasting fresh breath, you don't need to gargle all day, you just need the 12 hour antibacterial protection of Colgate Plax. Next, our hero uses the brand as a demo sequence describes how Plax keeps killing bacteria for 12 hours. In the end scene our hero is no longer gargling, but he and his female companion laugh at another couple who are.
