Where would the play be resumed from?

This is a throwin violation, so it goes back to the original throwin spot.

7-6-2: … The throw-in pass shall touch another player (inbounds or out of bounds) on the court before going out of bounds untouched.
PENALTY: (Section 2) Following a violation, the ball is awarded to the opponents for a throw-in at the original throw-in spot.

With definite knowledge, which you seem to have, reset the game clock to three seconds.

5-10: ART. 1 The referee may correct an obvious mistake by the timer to start or stop the clock properly only when he/she has definite information relative to the time involved. The exact time observed by the official may be placed on the clock.
ART. 2 If the referee determines that the clock malfunctioned or was not started/stopped properly, or if the clock did not run, an official’s count or other official information may be used to make a correction.
