Sally Blevins is on the trail of correcting the biggest mistake of her life: letting the Inferno-babies slip from her grasp, which lead to the complete derailment of her life. Now, having discovered the babies ended up with SHIELD, Sally has decided to join the organization in order to discover what happened next. Meanwhile, her companions Joe (a limbo-demon involved in the original kidnappings and looking for redemption) and Derek Moseley (a small-town sheriff who may harbor some very dark secrets) are investigating from their end… or are they?
