Series following people who protect and work closely with wildlife and domestic animals. RSPCA Inspector Mike Scargill is called to an abandoned flat in Derbyshire, whose only inhabitants are a dead dog and a dead hamster. A team from Hessilhead Wildlife Rescue Centre attempt to save an injured fox. And we spend the day with The WildCru, students from Oxford University, as they continue a programme of re-introducing the vole, one our rarest mammals, back to our riverbanks.
