The Shark Who Knew Too Much (1989)

Samuel Plottner is a stockdealer who only wants to get richer, but suddenly things starts to get complicated: His sons meets their longlost mother which not only is after Samuels money, but also can tell them what happened to them the day they were born. The financial expert Benny Hörnsteen is also after Samuels money, and so is the clown Conny Corny and Lennart K. Brons too. How will this end?
