Party enthusiast Thomas Ticker introduces young children who are preparing to celebrate religious and cultural festivals in the UK. Brother and sister Berzin and Benifer from London are preparing for Norouz - a festival celebrated by Zoroastrians and which marks the beginning of the year in the Iranian calendar. They paint eggs, grow wheat seeds and visit their Fire Temple. There is the traditional story of Jamsheed, the kind shepherd who rescues people and animals - surviving a long and harsh winter in a cave. And Thomas Ticker tries to clean his messy house and ventures outside his house for the Let's Celebrate Street Party Song!
