From SyFy's website:
"The series follows the shrewd and confident FBI agent Audrey Parker (Rose) who has a lost past, and arrives in the small town of Haven, Maine on a routine case. Before long, her natural curiosity lands her in the epicenter of activity in this curious enclave, which turns out to be a longtime refuge for people that are affected by a range of supernatural afflictions.
As the townspeople's dormant abilities begin to express themselves, Audrey helps keep these forces at bay while discovering the many secrets of Haven — including one surrounding her own surprising connections to this extraordinary place."
Here's a clip for season 3. Again, the series starts Sept 21st.
