In the video, there is a large group of wildebeests crossing a river. The water is brown and choppy, and the wildebeests are moving quickly through it. Suddenly, a lion appears and attacks one of the wildebeests, causing a commotion among the herd. The lion is tawny in color and can be seen biting and pulling on the wildebeest. The wildebeest struggles to escape, but the lion is too strong and manages to bring it down. The other wildebeests continue to cross the river, seemingly oblivious to the attack. The video captures the raw and wild nature of the wildebeest migration, as well as the predatory instincts of the lion.
