Swamp lions (2011)

The Swamp Pride is on its knees. Its mighty male was killed by poachers, leaving three mothers and their cubs defenseless in one of the toughest landscapes for a lion in Africa. Busanga Swamp is a quagmire, even in the dry season. Hunting in shoulder-deep water is all but impossible, and deadly hippos and crocodiles patrol the ever-present waters. Keeping cubs alive here is hard work, but for these lionesses it just got even harder: two massive young male lions are hunting them down. The males want to claim the Swamp Pride and its territory as their own, but to take over a pride they must kill its cubs. The mothers must fight tooth and claw to make sure that doesn't happen
