“Doomsday” seed vaults- the grail for post apocalyptic treasure hunters?

I’m knocking around ideas for a post-apocalyptic action-adventure story, to be done as one of Garth Owen’s alternate takes on popular film subgenres. The tale will be in the vein of Mad Max and all its imitators, with a band of adventurers, rather than just the one, traveling the post climate change/war devastation trading technology and information. What they want, more than anything else, is to uncover one of the underground seed banks, because the trove in there will set them up for life.
