When the body of a man is discovered in a garage with the engine of his car still running, it appears at first to be a simple case of suicide. The victim worked as a volunteer at a helpline centre dealing with potential suicide victims, and his wife is adamant her husband would never take his own life.
Da Derek McGrath findes død i sin parkerede bil, tyder alt på, at han har taget sit eget liv. McGraths kone nægter dog at tro på, at hendes mand kunne finde på at begå selvmord - ikke mindst fordi han arbejdede på en hjælpelinje for selvmordstruede. Det bliver en sag for Taggart-holdet, der vender søgelyset mod hjælpelinjens øvrige medarbejdere.
