Captured 2 men screaming for help after being caught in the undertow in the surf at the beach in Cancun, March 3, 2015.
The 2nd guy was in the biggest trouble, barely hanging on and going underwater several times. He appeared to be rescued just in time.
Both men ended up being OK. 2nd guy was given oxygen by the lifeguards when he reached shore, and paramedics arrived shortly thereafter.
Scary stuff. Be careful out there!
