If anyone can help me on this I would greatly appreciate it. I have this film in mind where a teenager learning martial arts at the lower levels comes across a ring somehow an can't get it off his finger, however, the ring makes him better at anything he does, the boy then meets an old man who tells him a story about the ring an that an evil guy is after it to put it with the ring he already has and make himself more powerful. That's all I seem to be able to remember an its bothering me.
