A man is on a skating rink with his left knee up and his right knee on the ice as he slides and pushes an object.  The object slides between two men who are moving something back and forth on the ice as the object follows behind it until it stops.  A man near them has fallen and he gets back up.  There are various people on the rink, most are upright doing their own thing on the ice but there is one person in a wheelchair.
