Starring Erin Chambers, Rachel Emmers and Bettina Schwarz, the film is based on the experiences of Heidi Johnson while working as a missionary in Austria for the Church of Jesus Christ of Latter-day Saints.

[2] Sister Rachel Taylor (Erin Chambers) of Boise, Idaho is an eager young missionary of the LDS Church who has been sent on an 18-month-long mission to Austria.

Taking a note from the very teachings she is trying to spread, Rachel eventually learns to accept others' differences and get along peacefully with her companions even if they disagree on how to go about conducting the work for which they volunteered.

[5] Vice compared The Errand of Angels to The Best Two Years finding them similar in story and structure although believing that the former would be better had it contained some of the humor and light-heartedness found in the latter.

[5] Richard Propes of The Independent Critic called the film an "insightful, touching and funny story" and he commended the director claiming that "Vuissa paints a richly human portrait of Sister Taylor".
