This groundbreaking ATV children's drama memorably blends hard science and fantasy in its tale of two teenagers who discover the existence of a 'time barrier' enabling them to travel to different periods and locations from World War Two to chilling visions of the future. Devised by Ruth Boswell who would go on to produce both The Tomorrow People and Shadows, Timeslip was unabashedly intelligent and often prescient in its theme of the use and abuse of science. Three children have vanished from the tiny Midlands village of St Oswald. First to disappear is local girl Sarah, then Simon Randall and Liz Skinner, who are on holiday with Liz's parents. Only Commander Traynor, an apparent stranger to the area, can offer some idea of where they are and that idea is so incredible and horrifying that the Skinners cannot believe it...
