Redemption is the 1613rd episode of The Bill.
P.C. Clarke unsuccessfully applies for a police loan. P.C. Taviner buys her a pushbike and suggests she sell her scooter, but she is far from impressed. P.C. Carver and P.C. Rickman find a young boy, Gavin Billson, overdosed on drugs, and CID investigate some of the local dealers. When it turns out Gavin overdosed on diamorphine, and after several dead ends, suspicion falls on Dr Stuart Bremner, a doctor at St Hugh's, who is also the boyfriend of Clarke's friend Ruth. A review of the hospital's CCTV footage reveals Ruth herself sneaking into a storeroom, and Clarke is forced to arrest her friend.
