Summary
Jack Robin, plagued by an agonising toothache, halts his motorcar before the modest residence of Dorothy Mason, whose melodic voice drifts from an open window. The moment he notices a deflated tire, he secures his automatic pump, then, entranced by Dorothy’s aria, forgets the task entirely. The tire’s sudden rupture sends Dorothy sprinting to the roadside, where Jack, feigning a limp, solicits her compassionate care. Their brief, intimate exchange is shattered when Dorothy’s father discovers that a set of crucial invention schematics has vanished. Harlan Graves, the family’s ambitious suitor, insinuates that Jack is the thief, prompting the protagonist to infiltrate Graves’ domicile in a desperate bid to exonerate himself. Inside, he encounters the notorious cat‑ burglar “Spider” Kelly, who, amused by Jack’s naiveté, adopts him as an unwitting apprentice. Together they storm a lavish house party, detonating a safe that they suspect houses the missing plans. The explosion yields the documents; Graves is apprehended, and Spider, disillusioned by Jack’s reckless demolition, departs, leaving Jack and Dorothy to contemplate a future unburdened by deception.
Synopsis
A terrible toothache causes Jack Robin to stop his automobile in front of the home of Dorothy Mason. Noticing a flat tire, Jack attaches his automatic pump and forgets about it as he listens enthralled to Dorothy's singing. When the sound of the burst tire brings Dorothy running out, Jack feigns injury so he can be nursed by her. After he leaves the house, and Dorothy's father discovers some important invention plans missing, Harlan Graves, Dorothy's suitor, suggests that Jack stole them. Jack, suspecting Graves, breaks into Graves' home to clear himself and meets a real burglar, "Spider" Kelly, who adopts Jack as his guide. They blow up a safe at a house party where Jack suspects the plans to be hidden. The papers are found, Graves is arrested and Spider, disappointed that Jack made such a mess in blowing the safe, goes off, leaving Dorothy and Jack happily alone.
