Gold Diggers (2015)

A newly-acquired tiger shark at a local marine park regurgitates a ring finger and part of a left buttock. When the remains are identified as missing multi-billionaire Clifton Randal, his four ex-wives converge to claim their share of his massive wealth. But Clifton is one step ahead of them: in a bizarre twist, he leaves only his deeply indebted six-star Gold Digger's Casino to his four ex-wives. So where are the missing billions?
