Shadows on Oak Island

Haunted by the loss of their son, an affluent Toronto couple, Rene and Jackson, retreat to the island to save their crumbling marriage. Wally, a chatty local and guardian of the island helps them adjust to their new home. Rene is desperate to solve the mystery of the island as Jackson numbs his grief with alcohol. She is convinced the treasure (The Holy Grail) will reunite them with their son. Wally, a self-professed expert on Oak Island agrees to help Rene in her quest. Wally, obsessed with finding the treasure since boyhood, at first sees Rene as a means to achieving his goal. Quickly, his obsession shifts to Rene and he appoints himself as her protector. Oak Island initially welcomes Rene and Jackson, then appears to be conspiring against them. Tensions heighten as the truth about Matthew's abduction, the treasure, and Wally are revealed.
