'When Calls the Heart' Sneak Peek: Jack's Mother Comes to Town

Daniel Lissing and Brooke Shields

Jack (Daniel Lissing) welcomes an unexpected visit from his mother Charlotte (Brooke Shields), while Elizabeth (Erin Krakow) struggles to find common ground with a woman who is so different from herself in a brand new episode of When Calls the Heart, airing Sunday, April 3 at 9 p.m. ET/PT on Hallmark.

Meanwhile, Rosemary (Pascale Hutton) enlists help from the townspeople as she plans her perfectly over-the-top wedding to Lee (Kavan Smith), before worrying whether they are compatible after all.

Elsewhere, as bad weather moves in, it threatens the surrounding land of Hope Valley, and the hard-working settlers and their families could face a terrible fate.
