Chris Jenkins, new to film-making, shoots footage of his two daughters – Vanda and Barbara - in Bute Park where they find a natural swing near Gabalfa Lodge and encounter a horse near Canton Bridge. They move on to explore the dereliction of the Glamorganshire Canal in the company of an adventurous boy, who dares to set foot on a rotting barge. Chris Jenkins also films fellow members of the Cardiff Amateur Cine Society at the canal, one of whom adjusts his – Chris's – tie.
