Caley Thistle squandered an early lead to suffer a 3-1 opening day Championship defeat at Dunfermline.
Inverness made a dream start through Nikolay Todorov, however the striker was withdrawn shortly afterwards through injury.
The Pars levelled midway through the first half through skipper Euan Murray, with late strikes from Ryan Dow and Declan McManus sending the Highlanders home empty-handed.
Inverness made three changes from the side which faced Cowdenbeath in the Betfred Cup in midweek, with Mark Ridgers, Scott Allardice and Todorov drafted in to replace Cammy Mackay, James Vincent and the injured Miles Storey.
Caley Jags took the lead after less than 90 seconds when Daniel MacKay sent in a low delivery from the right which picked out Todorov, leaving the Bulgarian with a simple finish past Owain Fon Williams from close-range.
The Pars looked for a quick response, with McManus and Dow both off target with headers.
Inverness were dealt a blow when Todorov limped off following a collision with Murray on 19 minutes, with Vincent brought on in his place.
The Pars levelled four minutes later, with Murray rising home to bullet home Dom Thomas’ corner with a close range header.
There was no further breakthrough before the interval, with Pars midfielder Iain Wilson firing over following another Thomas corner, while at the other end Caley Jags skipper Sean Welsh sent a low drive wide from long range.
The Pars started the second half brightly, with Kevin O’Hara seeing an effort blocked by Brad Mckay, before the former Alloa forward set up McManus who saw his near post effort blocked by the legs of Ridgers.
Former Inverness goalkeeper Fon Williams came to the Pars’ rescue on 69 minutes when he got down to deny MacKay following Allardice’s corner.
The Pars turned the game on its head on 78 minutes, with Dow reacting quickest to prod home the rebound after McManus had seen his effort blocked by Ridgers.
Inverness looked for a late leveller, with James Keatings sending a free kick well over before seeing another set piece blocked by the wall.
The Pars broke for a third goal with six minutes remaining, with McManus shrugging off Mckay before angling a deflected effort high into the net past Ridgers from just inside the box.
