We haven’t seen much from the Contingency Plan, the dance collective launched by Vanessa Goodman, Jane Osborne, and Leigha Wald. But what we have caught, at venues like Dances for a Small Stage, we’ve liked. Now the group is staging Submerged, an ambitious program on Tuesday and Wednesday (October 6 and 7) at the Roundhouse Community Arts and Recreation Centre. Highlights include celebrated veteran choreo ­grapher Serge Bennathan’s SLAM2 and promising choreographer Justine Chambers’s Caesura, as well as Rob Kitsos’s Distance and Jude Wong’s Out of Dodge.
