Devlin (1974)

After shows in Phoenix, Hank's circus travels to Desert City, Arizona. Along the way, the border patrol stops to inspect if there are any illegal immigrants boarding the circus caravan. When arriving in Desert City, the Devlins discover a stowaway (and runaway) named Juan. Juan wants to be part of the circus by helping Floyd out with the animals, since he's good with animals. But Hank tells him that since he's a minor and his tourist visa expired, he can't work. Juan explains that he ran away from Mexico because his dad wanted him to be a lawyer, like he is, but Juan likes working with animals a lot better.
