Sleepwalking Through the Mekong follows Los Angeles based band Dengue Fever on their recent journey to Cambodia to perform 60s and 70s Cambodian rock n' roll in the country where it was created and very nearly destroyed. The odyssey is a homecoming for singer Chhom Nimol and a transformation for the rest of the band as they perform with master musicians and record new songs along the way. More than a rockumentary, the film serves up a portrait of modern Cambodia as the band tours through Phnom Penh and beyond, crossing a great cultural chasm with the same spirit of Cambodia's original rock pioneers.
