This animated children's program follows the adventures of the title hero and his colleagues as they protect the citizens of the Welsh town of Pontypandy. Whenever the alarm sounds, brave Sam and his co-workers can be counted on to jump into a fire engine, hop onto a helicopter, or even launch an inflatable lifeboat to battle blazes, mount rescue missions, or provide medical attention to those in need. The episodes not only teach valuable lessons on fire safety to young viewers, but reinforce the importance of staying calm during an emergency.
