Centuries ago, Morgan Pym made a deal with Satan: his soul, in exchange for 10 years with his one true love. After she died, Morgan--desperate to avoid eternity in hell--agreed to become a Collector, charged with collecting souls from those who had made deals with Satan. Morgan's deal with the devil includes one additional clause: Morgan is allowed 48 hours with each client to try to redeem them before they are condemned to hell.
