A mysterious iron chest arrived on the island of Symi, Greece in 1882 and was immediately hidden for its own safety. 121 years later and Jason is working as a holiday rep for SARGO holidays. When his grandmother turns up as one of his guests she brings with her a locked cigarette case, left to Jason by his recently departed grandfather and given to him on Symi in 1944. The case is opened and reveals a piece of music, but the music is not what it seems and Jason and his small group of pensioners soon realise that they have stumbled on a secret that has been kept hidden on Symi all these years. A secret both dangerous and valuable. Jason and the Sargonauts is a contemporary comedy adventure full of fun and mystery, 'A comic, camp and musical romp.'
