They are entrusted with protecting the Energems from a fierce bounty hunter named Sledge, who has returned and is more determined than ever to capture the Energems for himself.

When one of Sledge's monsters manages to break the Rangers' bonds of friendship, it's up to Riley and Koda to remind their team what they truly mean to each other.
