Taggart S08E01 - The Hit Man 1992

Jimmy Catto, a professional hitman, is released from jail after 20 years. Shortly afterwards, his brother, Tommy, dies in a plane crash, but it was no accident. As Taggart launches a murder investigation, murky business dealings are uncovered in the Catto hotel empire, and Tommy's daughter, Ailsa, is threatened at gunpoint. When more murders are committed, they bear the trademarks of Jimmy Catto, but could he really be back to his old ways?
