Luke and Michael are gay. There's only one problem with that, and the problem is enormous.
Their entire small, usually peaceful, town is against gays. There's even a gang that will beat and kill gay people if they find them.
Luke isn't exactly the perfect Prince Charming. He deals drugs and basically works for a gang.
Michael is sweet, and almost completely innocent. He tolerates Luke being out late and smoking because he trusts and loves Luke with all of his being.
