"Bridge" is a short film, part of the "Fear You Can't Forget" advertisement campaign for Resident Evil 5. Its story was not written or overseen by Capcom Co., Ltd.'s BIOHAZARD development team, so is not canonical.
Chris Redfield drives to a bridge. Upon exiting his vehicle he climbs onto the edge, in preparation to jump onto the railway tracks beneath. An alarm sounds and causes him to have another attack of his Posttraumatic stress disorder. This time he imagines the word "Kijuju" has been cut through his arm.
