Could do with more of a "storyline" (e.g. Lions & Hyenas, Mortal enemies) but as a "general" film of tigers it's ok.

We watch with forest rangers as Lakshmi raises her triplets to sub-adult. Then, ominously, the remains of the triplets' father are found - he had been patrolling territory overlapping Laksmi's and had been killed by another male.

Then, one shattering day, the rangers find Lakshmi wounded, presumably at the hands of the stranger male. As this was natural and not the work of man (i.e., poachers), they do not intervene. She then disappears, and tension rises as time goes by with no sign of her. Is Lakshmi alive? What of the cubs, the hotheaded boys and their more competent sister? I'm not telling - watch and find out! Another gem in NG's cap.
