Tammy Lane, mother of 4, left behind her husband and kids to make a difference for those less fortunate in India and Africa.

Tammy has been married to her husband, Britt, for 21 years and the couple has four children; Jade (20), Dillon (17), and 13-year-old twins named Savanna and Destiny.

"I was a stay-at-home mom until about four years ago. Once my kids got older I wanted to fulfill a purpose...a year prior to the trip, I was watching TV and saw a program about leper colonies in India. I was shocked to see they still existed. From that point on, I wanted to go over there and help the people. That's what put the idea into my heart to do something."

Take a look at a recap of Tammy's month long journey.

Tomorrow, we follow-up with Tammy and her family and check-in after the trip.
