The series, which is based on Jonathan Stroud's young adult supernatural novels of the same name, follows a trio of teenagers working for ghost-hunting agency Lockwood & Co.
Together, they set out to investigate some of the spookiest and deadliest spectral hauntings in London.
The official synopsis reads: "In London, where the most gifted teenage ghost-hunters venture nightly into perilous combat with deadly spirits, amidst the many corporate, adult-run agencies, one stands alone: independent of any commercial imperative or adult supervision – a tiny startup, run by two teenage boys and a newly arrived, supremely psychically gifted girl, a renegade trio destined to unravel a mystery that will change the course of history: Lockwood & Co."
