Dot Dot Dash

A mysterious encrypted message appears one night in Mark's radio as he searches the sky for news from his father, a captain supposedly lost at sea. Instead, Dune's cries for help, in Morse Code, fills his headset with beeps. In a hurry, he translates them to discover it is not his father like he'd always wanted - but something nearly just as important. Mark has just days to save Dune before his own world crashes down around him.
