In 1993, a group of students and teachers from a Welsh secondary school visit St Petersburg to learn about Russian art, and to discover themselves in the process. Communication difficulties lead to the students and teachers becoming separated before they reach St Petersburg. Made by S4C in 1993, this was the first time that a Western crew filmed in Russia after the breakup of the Soviet Union.
From IMDB: Seven teenagers and three teachers from a Welsh school visit Russia in a bid to rediscover themselves. On the overnight sleeper service to St Petersburg the students get separated from the teachers, which allows the students ample scope for rediscovery.
