Alpha is an epic experience during the last Ice Age. Europe, 20 000 years before. In the middle of his first pursuit with the top of his clan, a young man is wounded and left for dead. When he wakes up, he will feel fragile and lonely, and he will have to figure out how to survive and advance before ruthless and ruthless nature. Reluctantly joined by a wolf deserted by his haste, they will confide, progress to partners and defeat the innumerable perils to, in all likelihood, discover the road before the landing of the dangerous winter.
