Where can I watch Heaven's Door in United States?

12-year-old Riley Ann Taylor recently lost her grandfather, who died right in front of her while teaching her how to play soccer. She soon finds a portal leading to the place people talk about but never see: Heaven. She gains a miraculous healing ability and uses it to help those who are sick but soon gains the diseases these people and animals had. You know what they say, every good thing comes with a price.
