Like several other Doctor Who stories, it was set in World War II. Unusually, however, it took place late in the war, about a month after the Battle of Monte Cassino, in a northern Italian village whose inhabitants were partisans. Of the many glimpses of World War II provided by Doctor Who, Treasure Trail may be the only one set amongst the Italian resistance.
The Time Lords send the Fourth Doctor and Sarah-Jane on another mission without clear instructions. They find themselves under Nazi aircraft fire almost immediately upon disembarking the TARDIS. The Doctor's people have dumped them near the northern Italian town of Borosini in the summer of 1944.
Suspected by the local villagers of being Nazi spies, they are brought before the town's priest, Father Antonio. The Doctor convinces the priest they are English, using the writing on the TARDIS' police box exterior as proof. Any doubt about the pair's identity, however, is far less significant than that Goering's Nazis are entering the village. It seems they are after whatever artistic treasures they can find.
They storm into the church, and Antonio shows them the Raphael hanging in the knave. Impressed, Lieutenant Schuler spreads word of the painting up the Nazi chain of command. Meanwhile, the villagers fear that the Nazis will just steal their art as they've already done elsewhere in Europe. The Doctor offers his aid and wins Antonio's trust by bringing him forward in time to 1976, so he can see the rebuilt Monte Cassino monastery.
Giovanni, a local partisan who has given the Doctor and Sarah a hard time, confirms that there's a massive shipment of stolen art soon to pass through by train. The Doctor proposes to blow the line. They do this, retrieve all the stolen art via a mule trail, and bring it all back to the TARDIS. The Time Lords send the TARDIS to April 1948, where the Doctor offloads the art. To the Italian press, it seems as though the art has magically reappeared. Only Antonio and Giovanni in Borosini knows it's not magic, but it's a secret they vow to take to their graves.

to be added
- This story makes no significant references to other DWU fiction, although it does follow on from The Dalek Revenge and Virus, with the TARDIS still under the control of the Time Lords.
- It is never explained why the Time Lords deem the Italian treasures important enough to send the Doctor to save them. However, in the later audio story, Fallen Angels, the Fifth Doctor refers to the works of Raphael as a fixed point in time. Another audio story, Operation: Hellfire, shows that the Time Lords have sent the Doctor on a mission during the Second World War once before.
- The Eleventh Doctor again used the writing on the TARDIS' police box exterior to prove that he was from London when he met Adolf Hitler in Berlin in 1938. (TV: Let's Kill Killer)
