Police chief Xavier Quinn investigates the gruesome murder of Donald Pater, one of the wealthiest residents on a Caribbean island. He was found decapitated in his Jacuzzi. Although the local political establishment, especially crooked Governor Chalk, insists that small-time thief Maubee is responsible, Xavier has his doubts. This view is complicated by the police chief's personal history with Maubee: The men have been friends since childhood.
Unfortunately the movie The Mighty Quinn is not yet available on HBO Max.
