Curious friends Kojo, Ama, Yaw<br \/>\nand Esi notice lights being left on everywhere \u2014 in schools, shops and empty corners \u2014 and realise the town is wasting electricity. If nothing changes, the situation could get worse. So<br \/>\nthe children investigate, talking to neighbours, visiting the town council and collecting clues. As tension rises and Obuasi faces a real threat of blackout, they must use clever ideas, teamwork<br \/>\nand courage to help everyone understand that small actions \u2014like switching off lights when not in use \u2014 can make a huge difference.
