Alarm für Cobra 11

Who made an attempt with broken bus bringing police team to a bowling game? Dieter's old friend Fallada who was at the wheel and whose business is going not so well? A more successful businessman Bresser who aggressively wants to buy his business? Fallada's wife who's more willing to sell it? Or her young lover Axel formerly working for Bresser? Or is there somebody else interested in compromising them all, one dead, others accused of their death, and the guilty with big money somewhere at the sunny beaches? Not so simple to understand especially when Fallada is found...
