A series of bizarre drug-related deaths among runaway teenagers has set the North East's homeless community on edge.

 The word on the street is that a rogue batch of Spice - the zombie drug sweeping the inner cities - is to blame, but when one of Jimmy's few close friends is caught up in the carnage, loyalty compels him to find out what's really going on.

 One Way Street sees the welcome return of Jimmy Mullen, the homeless, PTSD-suffering, veteran as he attempts to rebuild his life following the events in The Man on the Street.

 As his probation officer constantly reminds him: all he needs to do is keep out of trouble. Sadly for him, trouble seems to have a habit of tracking Jimmy down.
