An Arizona couple found themselves stuck in the sewers after wandering for hours in search of a doomed puppy.
According to the Phoenix Fire Department, the man and woman in their 40s said they had seen the puppy fall into a storm drain.
They promptly followed it in an attempt to rescue the dog, although authorites said they did not know how the two adults got inside.
"[Storm drains] are actually built to keep people out so this exact thing does not happen," a representative from the Phoenix Fire Department told InsideEdition.com.
They had been reportedly walking around 16-feet underground for hours, both in search for the puppy and for a way out when a passerby heard screaming as he was biking past the block, and dialed 911.
"They're lucky that somebody actually heard them screaming for help," the rep said, explaining the toxic air within the sewers can make it a very dangerous place to be.
Officials promptly arrived and pulled the pair to safety in an hour-long rescue.
The couple was not injured. However, they never found the puppy.
