Who will come out on top in this epic battle for survival? Whale Wars returns for a fifth adrenaline-fuelled season, and this time the representatives of the Sea Shepherd Conservation Society face their biggest challenge to date as Japanese whalers return to the waters with a huge bankroll to finance their operation.
