Paul Nicholas, Sheila Ferguson, Wayne Sleep and Jan Leeming embark on an adventure in the capital of Argentina, Buenos Aires, first paying a visit to a late night Tango event where they spend the night dancing with the locals. The following day, the group explore what the cultural capital of Argentina has on offer. Having duetted together in the past, Sheila and Paul book a Tango singing lesson, while Wayne and Jan enrol in a life drawing class. For their final night in Buenos Aires, Sheila and Paul find a venue where they can perform the Tango song they learned earlier in the week.
