Quite possibly Angel's greatest scene ever. The name of the story is actually "Damisela en Desgracia", which is Spanish for "Damsel in Distress". Quite a fitting title, as pretty much every page has bondage in it.
Anyway, Angel is all suited up to go investigating (not sure what, but she needs "evidence"). She has a lead at an abandoned factory, and naively runs over there. She encounters a mysterious boy, and immediately falls into a trap.
The fall knocks Angel unconscious. When she wakes up, she is tied up to a pulley and gagged. This goes on for many panels until she is rescued.
