This is an old favorite of mine that I feel compelled to revisit every so often. The movie was directed by Raj Khosla of CID (1956), Woh Kaun Thi (1964) and Mera Saaya (1966) fame, and according to IMDB this was his 5th straight direction of a Dev Anand starrer. The movie stars, besides Dev Anand in his Gregory Peck style hair-puff days, a lovely Suchitra Sen, the usual assortment of character actors and wonderful music by S. D. Burman.
The movie tells the story of Babu (Dev Anand), a small time crook in Bombay who accidentally kills fellow crook Balli (Jagdish Raj). Horrified by what he's done, Babu flees and doesnt stop running till he reaches Jogendranagar, a small town in the Himalayan foot hills.
