Murder Magnetic (2021)

Arriving home one morning, film composer Lewis Kerwin finds a cassette tape in an envelope outside his door. To his, and his partner Lucy's horror, the tape contains a recording of a horrific murder. The same day, an American detective named Franco arrives in the town to investigate the case, and inevitably, their paths cross. As Kerwin and Franco both conduct their own investigations, the body count begins to rise, and Kerwin's involvement becomes increasingly suspicious. With Kerwin's obnoxious manager George looking like the prime suspect, Kerwin quickly realises that whoever is behind the slayings may be closer to home than he'd like.
