HE WAS most certainly an agent of salvation. Hell Jumper (BBC2, Wednesday of last week) told the story of Chris Parry, 28, from Cornwall, so appalled by Putin’s invasion of Ukraine that he immediately dropped everything and went to help however he could.

He had no military experience, had never fired a gun, spoke no Ukrainian: in Lviv, he found thousands of other volunteers similarly motivated, all travelling in from around the world, in contrast to the huge exodus of citizens desperate to get out to safety. He became a “Hell Jumper”, driving into the heart of the conflict to rescue those too elderly, ill, or stubborn to have left earlier.

The rescuers’ work, and this documentary, was conducted entirely on mobile phones and bodycam. Gathering the volunteers, relatives’ desperate pleas for someone to rescue their aged relatives, the very identification of the addresses where they were sheltering — all were achieved (without any military or official backing) through mobile phones, Google maps, and translation apps.

For technophobes like me, this is a sobering eye-opener, a movingly positive work by something that I instinctively class negatively. The rescues are all recorded on bodycams; the footage is then broadcast to raise support and funding to buy vehicles and equipment. We watched, as it were, over the shoulder of Mr Parry’s grieving parents, who were forcing themselves to view the footage to get closer to their son’s incredible bravery, foolhardiness, and commitment to people (he evacuated more than 400) with whom he had no connection whatsoever.

Despite falling in love with a lovely Ukrainian, he grew bolder and rasher: when the vile Wagner Group released his bullet-ridden body, they insisted that he was a foreign mercenary. The banality of shattered housing estates, tower blocks blitzed to smithereens, searingly depicted the worst that human beings can do to each other, redeemed by the very best.

Acting leached into real life for Will Mellor: his role in the docudrama depicting the Post Office scandal (TV, 12 January) so affected him that, as Surviving the Post Office (BBC1, Monday of last week) demonstrated, he now supports and fights for its victims. Appallingly, the suffering continues: the guilt, the shame, the anger, the burdens carried by spouses and children ostracised by communities and vilified by local media. But did you know that sub-postmasters must still use Horizon, still registering errors, if usually writing them off: so far, there’s no alternative.

My stepdaughter champions Netflix’s series America’s Sweethearts, saying that it has profound theological content. Fervently believing that “God is in control of this whole process” may not be an entirely appropriate credal statement to describe auditioning for the Dallas Cowboys football teams’ immaculate cheerleaders — a queasy blend of erotic stimulus and apple-pie wholesomeness — but their skill and enthusiasm could be just what is needed to revive your liturgical dance group.
