Episode 5 in Terence Wrong’s eight-part medical documentary series runs a wide emotional gauntlet. On one end, there’s the touching drama of a brother who sacrifices half of his healthy liver to try and save his brother (putting both their lives at risk in the process). On the other, there’s Ben van Boxtel (left), an E.R. doctor who handles incoming emergencies with seeming aplomb – but drops his cool façade when victimized by a prank from co-workers.
