Just as the sophistication of Shanghai in the 1930's has been revived as a symbol for the new China, so too does "X-Roads" take its inspiration from the past... "X-Roads" is a modern romance, but uses original footage from Chinese classics as flashbacks to reveal a secret that affects the fate of two young lovers.
