Cartoonist and writer Dylan Horrocks heads to England to trace his family lineage in this documentary, which mixes science and history. Horrocks uses DNA analysis to investigate if he is related to 17th century English astronomer Jeremiah Horrocks. In 1639 the scientist was the first person to observe the Transit of Venus. This planetary movement prompted Captain James Cook to travel to the Pacific. Horrocks heads to Tolaga Bay to view the transit in 2012, a special moment as the next one will be in 2117. The 70-minute film is directed by Dylan's stepmother Shirley Horrocks.
