Kids In Crisis, Channel 4, 10pm

One-off documentary about children with mental illnesses and the difficulties they and their families face in getting the right kind of treatment as welfare budgets and local services are cut across the UK. Director Alison Millar turns her camera on four such children: 13-year-old Oli and 17-year-old Chloe, who have to travel out of their native Cornwall to receive treatment because there are no psychiatric beds in the county any more; 15-year-old Beth, who is treated 120 miles away from her Hill home; and Emily, who has to leave Northern Ireland and travel to England for treatment for an eating disorder. Heart-rending stuff.

Destry Rides Again, Film4, 5.20pm

Fans of Westerns have their hands full these days, with the daytime schedules choked with an awful lot of bad and ugly examples of the genre, and very few good ones. This, though, is in that last category, a classic from 1939 which pits saloon-dwelling Marlene Dietrich and her lawless boyfriend Brian Donlevy against the one and only Jimmy Stewart as Tom Destry. He's the son of the former sheriff of the town of Bottleneck, who rides in to find the place has taken a turn for the worse. So, despite not carrying a sidearm, he decides to clean up the mess - but not before Dietrich has sung a song or two.
