On The Streets is the 2371st episode of The Bill.
Mickey continues his undercover operation as a homeless man. He continues to gain the trust of Nicola Mackenzie, and CID find the Mis-Per's mother. Lenny Wiseman is found dead complicating things, and Mickey, Reggie Sharpe and Mackenzie are assaulted by Ryan Nelson, the prime suspect in the Jake Evans murder inquiry. Carter orders Mickey to take Nicola in, after Sharpe is brought in, as the new prime suspect. Mickey first refuses, but decides he will bring her in. When it appears she is not the murderer, and Mickey suspects it's someone else close to Evans and Mackenzie. CID discover Lenny died from a drunken fall, and property manager Greg Simm is off the hook.
