Instant replay

“20/20: In An Instant,” the only broadcast network show to shoot in Minnesota, won’t be back next season, but you can still appreciate the way local filmmakers used our state to re-create disaster scenes that happened across the country. In this weekend’s repeat, the area doubles for the San Bernardino National Forest, where an Army vet tries to survive a sudden blizzard.

Cold case

“Drew Peterson: An American Murder,” a two-part documentary, looks at the mysterious disappearance of Stacy Peterson and the husband who became the prime suspect. It remains a riveting whodunit, but the film might have you wondering whether as much attention would have been paid if the missing woman weren’t young, white and attractive.

8 p.m. Sunday and Monday, Discovery ID

Sketchy behavior
