Arquette will play Virginia ‘Gigi’ Cessna, Jenny’s (Winnick) charismatic, fast-talking mother. She’s a world-class scam artist who used childhood Jenny in her grifts, much to present-day Jenny’s resentment. Gigi has an uncanny ability to charm her way into people’s lives and then disappear without a trace. When she returns to Helena to pull her latest con, Jenny catches onto her and mother-daughter must work through their difficult relationship.
In Season 3, titled ‘Deadly Trails’, private detective Cassie Dewell (Kylie Bunbury), undersheriff Jenny Hoyt (Winnick), and newly appointed sheriff Beau Arlen (Jensen Ackles) maintain order in Helena, Montana with their unparalleled investigative skills. But when a local backcountry trip led by charismatic outfitter Sunny Barnes (Reba McEntire) goes awry, the trio faces their most formidable mystery yet – in which no camper can be trusted and where danger lurks around every jagged rock and gnarled tree.
