Two sisters who perform acrobatic stunts for money are actually thieves who are out to rob a "bank" full of silver and gold. The head guard at the bank is the "good" guy (But is he really?) who is challenged by the invisible loner, a rascal who is fairly close in kung fu and sword skills to the guard. It all comes down to a massive robbery of the "bank" in which these four plus some other men unfortunate enough to be involved (they meet their end somewhat quickly) results in the final four being so greedy they keep trying to kill each other until only one can possess the gold. And it's a lot of gold. There is quite a bit of gory swordplay including hacked off arms and legs and multiple blades to the chest and back with all the "red paint" blood Shaw is famous for. Like a spaghetti western this comes down to a whole lot of money and being a sister or lover isn't enough to save you from a good sword in the back (or front). I don't recommend this to those who hate wire work as there is a lot of it here. But if you enjoy good action and swordplay this is a good time with an interesting story.
