Episode 314 is the 1972 episode of The Bill.
DC Zain Nadir is certain that his cover has not been blown after Jordan Tomlin threatens Nadir of Covert Ops and Lance with a gun, and Okaro authorises him to meet drug dealer Joshua Armstrong. The intervention of an armed motorcycle passenger threatens to cut short the entire investigation. Honey returns from honeymoon and confides in Yvonne about a storage unit hired by new husband Scott Burnett. She finds a bloody glove, fuelling suspicions that he killed his first wife. Phil is furious with his brother Steve for telling Kate Maltby about his daughter Madison.
TJ Ramini is now credited as DC Zain Nadir, and listed among the regular cast, although he does not join Sun Hill CID until Episode 319.
