Close to the end of Solo: A Star Wars Story, Tobias Beckett first betrayed Han, then Dryden Vos, and attempted to keep the two cases of the refined Coaxium for himself. He took Chewbacca as a prisoner and abandoned Vos' ship leaving him, Han, and Qi'ra fight each other. Beckett and Chewie left on foot and ended up only on a sandy shore of Savareen.
But where was Beckett planning to go? He couldn't have been sure it was Vos, who got killed in the skirmish, and he most likely would have been after him soon. Still, there was nothing, no ship nor vessel of any kind, at least in sight, where he was heading to.
