Diamonds (1999)

In an effort to bond with his estranged son, Lance, elderly former prizefighter Harry Agensky takes his son and grandson on a road trip to Reno in search of 13 stolen diamonds, stashed away years ago. On the way there, the men visit a local brothel run by madame Sin-Dee, so that 15-year-old grandson Michael can lose his virginity. Following their quest for the hidden diamonds, both father and son learn a lesson about reconciliation and the price of growing older.
