It is Noel and Sue Radford's 30th wedding anniversary and they expect to celebrate it with a romantic meal, but their children have other ideas and are hatching a plan to send them on a dream trip abroad. But it is put in jeopardy when the Radfords' youngest refuses to be weaned off breast milk, and Noel is overcome with worry about leaving the bakery in the sole hands of Luke.

Noel and Sue mark thirty happy years of marriage with a very special – and eventful - road trip down memory lane. Spanning three decades, Sue and Noel visit the people and places that have shaped and affected them the most. Sue is surprised by her bridesmaids at the church they got married in, and is reminded of the fact that nobody thought the marriage would last. Little did they know! And Noel is made to relive his hilarious drunken antics at the reception. They also revisit the site of their first business, which nearly ended their marriage and left them bankrupt. But 30 years later and with 22 children, Noel and Sue wouldn't change a thing.
