When small-time heroin dealer Jai McDiarmid turns up dead one fine Glasgow morning, no one is that surprised - he'd been sleeping with a drug trafficker's girlfriend and had made himself a lot of enemies - so many, in fact, that Detective Superintendent Catherine McLeod doesn't know where to start when she is assigned to the case. Meanwhile, out-of-work actress Jasmine Sharp is doing her best to be a private investigator, but her PI mentor Uncle Jim, who was meant to be showing her the ropes, has just disappeared in mysterious circumstances. She begins looking at the open cases that Jim was investigating - which sends her into trouble, fast. And when she soon finds out that Jim's disappearance has something to do with Jai's death, she teams up with Catherine - and together they stumble upon an old open case which throws everything into question. In Glasgow, nothing is quite what it seems.
