Sons (1989)

Stepbrothers Ritchie, Mikey and Fred take their ailing father from an American veteran's hospital on a pilgrimage to Normandy, where he had seen action in World War II and once had a girlfriend. The trio - who spend much of the journey to France arguing - hang out in some of the seedier sections of Paris, where they meet a transvestite and also Florence, who captures Mikey's heart.
