Ostensible story is a soft and anticlimactic murder mystery. But don’t cling to the obvious if you care to avoid disappointment. Focus instead on the subtext - a woman who gets tacit erotic pleasure from playing cat’n mouse with each of 3 members of the family who is responsible for her son’s death. Lot’s of sexual tension from all directions here. Moka is an intriguing and exciting film from this perspective.
