Simi is sent to stay with her grandmother in a remote village deep in the forests of Nigeria. Witch-like and tight-lipped about the past, her grandmother hints at a tragic family secret - but won't tell Simi the truth. Simi is desperate to discover it for herself, but it's only when she's caught in the red quicksand of a forbidden lake that her adventure truly begins. Along with new friends, Jay and Bubu, Simi must bring her family back together and restore peace to the village.
