Two fancy-pants brothers return west after years of eastern schooling and almost immediately anger the local gang of murderous extortionists. However, the boys have an ace up their sleeves in the form of ultra-cool gunslinger Gianni Garko, a mystery man with a debt to pay.
After the first several minutes of pretty silly slapstick, things get good, with lots of amusing touches and a neat performance by Garko, dubbed into English by an actor sounding like he's doing an impersonation of Clint Eastwood!
Whenever Garko disappears too long though, the movie begins to suffer. Still, it's worth recommending for spaghetti western fans who've already seen everything.
I've noticed that other viewers seem to overlook the connection between the brothers and the gunfighter, why he's protecting them. It's actually explained quite early on, in pretty certain terms.
