Monty travels from Corfu, which possesses strong Venetian links, to the Greek capital of Athens, where he visits a reforestation project and two spectacular modern gardens.

Beginning in Trieste, Monty heads down the Croatian coast in the footsteps of the Venetians. He visits a public garden created by an obsessive plantsman and is given a tour of ancient olive groves.

Monty explores Venice by barge, stepping out to visit green spaces large and small, including gardens along the Grand Canal and in a disused rubbish dump.
