Troy Deeney's 96th-minute goal fired Watford into the npower Championship play-off final in the most dramatic fashion at Vicarage Road.
The Hornets' promotion hopes looked over when, 60 seconds earlier, Leicester were awarded a penalty.
But Manuel Almunia pulled off a stunning double save to keep out Anthony Knockaert's spot-kick, and also the rebound.
And as Watford broke up the other end the ball fell to Deeney in the penalty area to crash into an empty net and spark wild scenes of celebration.
Watford trailed 1-0 from the first leg and twice levelled the tie on aggregate through Matej Vydra, either side of David Nugent's header.
Vydra had not scored in his last 12 games but ended his drought in sensational style in the 15th minute when he crashed a superb angled volley across Kasper Schmeichel and into the net.
That levelled the tie on aggregate but Leicester got their noses back in front just four minutes later, Nugent out-jumping Lloyd Doyley at the far post to nod in Matty James' corner.
The goal Watford desperately needed came in the 65th minute when Vydra played a neat one-two with Deeney just inside the area and sidefooted his second past Schmeichel.
With extra time looming Cassetti nudged Knockaert to the ground in the area and referee Michael Oliver pointed to the spot. Knockaert was already celebrating in front of Leicester's fans but that proved premature when Almunia saved his penalty with his legs and got up in time to parry the rebound.
And as if that was not dramatic enough, Watford charged back upfield and moments later Jonathan Hogg's header back across goal was touched on by Vydra and Deeney gleefully slammed in the winner.
