Lost Boys is a documentary about damnation – about three men lost in a drug hell, defeated in the game of life, disappearing into the streets of Cambodia. Ten years ago the men enjoyed the success of Reindeerspotting, a film documenting their drug-fuelled life in Northern Finland. The party comes to an end when one of them dies a violent death in Phnom Penh. Joonas, the director of the film, is looking for his own truth about what happened among the drugs and the gloom.
