When Charlie's (Ryan Corr) best friend, Nate (Bob Morley), dies at just 38, Charlie is forced to face his grief in a way he could never have imagined, with the ghost of his dead friend ‘haunting’ him at his side. The buddies have to work out how to get Nate out of Limbo so Charlie can get on with life with the living - as he navigates a potentially complex romantic world with Nate’s ex-wife Freya and new love Lily, always with the witty and often unhelpful ghost Nate running interference.
