Miriam Margoyles, Wayne Sleep, Bobby George and Jan Leeming reunite to head to the hot and vibrant city of Havana, Cuba, where life expectancy is high, food is rationed and the way to travel is in iconic 50s cars. After being wowed by the pink Cadillacs that pick them up from the airport, the group spend their first night learning to dance with the locals. Later in the week, Wayne visits a dance troupe and realises his classical training doesn't count for much when it comes to learning Cuban dance. But much to his joy, he is invited to participate in the annual Cuban carnival. Meanwhile, Miriam struggles to adapt to life without high-speed broadband, although at least she still has gin. Perhaps the biggest change comes for Jan, who meets a Cuban man while sea swimming. Not put off by the language barrier, the pair decide to go on a date. As the visit draws to an end and the group celebrate with their new friends, there's time to reflect on life in this fascinating and fast-changing country.
