By Lucy Catherine.

Part four of the conspiracy thriller's final series.

A strange cannister recovered from the sunken ship contains seeds from the global seed bank. Helen and Freddy head to Svalbard, a remote island in the Arctic circle, to find out more. As storm clouds gather, nothing is quite as it seems in the darkening North.

A gripping thriller, Tracks was the first drama to hit the top of the iTunes podcast chart back in 2017. It went on to win Best Sound (BBC Audio Drama Awards) and Best Fiction (British Podcast Awards). Now Tracks is back with a fifth and final 9 part series.

All four previous series of Tracks are available now in full on BBC Sounds.
