Features Six-on-his-own getting involved with a computer salvage operation where there is more going on than first appears. It didn't really sing to me, despite the presence of big name stars like Giles Brandreth and Helen Atkinson Wood (and Sara Griffiths from Old Who).

Urgent Calls, on the same CD set as I.D., is a different matter. It's virtually a two-hander between Colin Baker, at the end of a phone line, and Kate Brown playing Lauren who keeps getting connected to him accidentally. In the space of thirty minutes we have two different alien manifestations and a certain exploration of what the Doctor is really doing. Very impressive. ( )
