Mexico has some problems. People leave Mexico to go to the US. They do this illegally so they can leave Mexico quickly. However, they cannot see their families again. It can be hard to get back to the US if they visit their families.
An organisation wants to help these people. It asks the leaders of the US and Mexico to open the border. The leaders open the border at one place along a river.
The organisation brings families together from the US and Mexico. They can meet for three minutes. They are very happy and very sad.
Difficult words: illegal (not following laws), border (a line between two countries).
