Check out Shirkers on Netflix. I really enjoyed it.
Heres a blurb describing it
In 1992, teenager Sandi Tan shot Singapore's first indie road movie with her enigmatic American mentor Georges who then vanished with all the footage. Twenty years later, the 16mm film is recovered, sending Tan, now a novelist in Los Angeles, on a personal odyssey in search of Georges' vanishing footprints.
