When the Road Ends (2020)

Growing up in poverty as a child, Dylan dreamt of travelling the world on a motorcycle. Many years later he broke the shackles of a normal life and took to the road. After journeying 200,000km across four continents, the road from Panama to Colombia comes to an end, swallowed up by an impenetrable jungle. Dylan has no choice but to take to the sea, building a raft powered by his motorcycle engine in the hope of reaching Colombia's road network 700km away. He must brave strong ocean currents and storm batterings in his journey from Central to South America.—Journeyman Pictures
