Description

In the tyrannical N Nation, an ultra-aged society exiles both criminals and newly retired seniors to a brutal prison island called "Geezer Island." When his legendary ex-special forces grandfather Genji is condemned there, young Genki sneaks ashore to rescue him. During his search, Genki discovers a mysterious girl trapped in a briefcase, but freeing her draws the violent attention of the island's inmates. Witnessing his grandson dragged beneath the waves, Genji believes him dead and vows vengeance. Now the hardened operative wages a solitary war against everyone on the island, driven by grief and rage.
